"Top IP67 Waterproof Micro Switch Suppliers in 2026: Where Each Supplier's IP67 Rating Stops"

At an automotive lock, a charging port or outdoor automation equipment, a buyer specifying an IP67 waterproof and dustproof micro switch has several prominent manufacturers to choose from. Wired into the product, the switch meets water and dust at the terminals and lead wires as well as at the switch body. A micro switch sold as IP67 carries the rating at the level the supplier's own pages state, whether for the named model, for the switch body with the terminals excluded or a condition attached, or for the company in general. For each supplier on the shortlist, a buyer gets the group the published evidence supports, the applications served by the supplier's IP67 switches and the questions to settle before requesting samples.

The supplier's own page sets how far IP67 reaches on a micro switch

An IP67 claim on a micro switch is a statement on a supplier's page, and the page decides which part of the switch the statement covers. The rating on these pages is the IP67 defined in IEC 60529, and suppliers attach it to different parts of the switch or to the company as a whole.

Water reaches a wired switch at the terminals and lead wires

A sealed micro switch takes water and dust at its terminal end as well as at its plunger once the leads are connected. A body sealed to IP67 with the terminal end outside the claim hands that joint to your product's own sealing. Sealing construction closes those paths in more than one way, and how each method works at the terminal cavity and the soldered wire exit is covered in our article on which micro switch manufacturers use low-pressure molding for waterproof sealing.

Three ways a supplier page states IP67

Model-level IP67 is a model or series page that states IP67 with no exclusion or condition attached. IP67 with exclusions or conditions is a page that rates the switch body and places the terminals outside, ties IP67 to a step such as wiring, or describes water resistance as equivalent to IP67. Company-level IP67 is IP67 named in a company introduction while the model pages describe the switch as waterproof.

The group tells you where a supplier's claim stops on paper. Whether the terminals sit inside IP67 on the part you'll actually order is still a question for every supplier, the model-level group included.

IP67 and a safety approval answer different questions

An IP67 rating answers whether dust and water get in, and a safety approval such as UL, ENEC (European Norms Electrical Certification) or CQC answers whether the part meets an electrical safety scheme. Product titles often run the two together, as in "IP67 Waterproof Micro Switch, UL Recognized Component". Each one can be held for a different model, or for the company, so a request names the model that carries each.

A product listing and a manufacturer's page carry IP67 differently

A marketplace listing is a sale offer, and a manufacturer's model page is the record a part number traces back to. Listings and wholesale pages put IP67 in the product title, often next to a safety approval, and the same switch can appear under several sellers. The suppliers in this article are placed only from pages published by the maker of the switch: model and series pages, datasheets and comparison documents, and company pages where those are what a supplier publishes.

Series names cross catalogs as well. G303 and WS1 each appear in more than one maker's range, so a series name on its own can lead to another supplier's part. A request that names the brand and the full part number brings back the datasheet for the switch you meant.

Model-level IP67, IP67 with exclusions or conditions and company-level IP67 across the suppliers checked

Most of the suppliers checked state IP67 on a model or series page as it stands, Kangerle, Omron and Unionwell attach an exclusion or a condition, and Dongnan names IP67 at company level, with suppliers in alphabetical order inside each group.

An exclusion or a condition written on the page is what moves a supplier out of the model-level group.

Model-level IP67

Daier

A waterproof range in which the miniature series carries IP67.

Daier's waterproof category lists switches "with protection levels up to IP67, electrical ratings from low levels up to 15 amps, and a wide operating force range of 50gf~400gf", and its miniature micro switch is "Designed for waterproof and dustproof (IP67)." On a category rated up to IP67, the rating belongs to the series that names it.

Best for: A position that needs an operating force picked from a wide waterproof range.

Where IP67 is stated: The miniature micro switch series on the waterproof category page.

Strengths

Operating force range of 50gf to 400gf across the category.

Electrical ratings up to 15 amps across the category.

Limitations

Category rated up to IP67, so the series is confirmed by name.

Donghai

Wire-lead IP67 switches catalogued by application.

The MT8 page is headed "MT8-IP67 Waterproof Micro Switch" and lists "UL&ENEC&CQC Safety Approvals", and the wider catalog under the DONGHAI brand sorts sealed switches by use, from "Waterproof Dustproof Micro Switch For Door Lock" to "Waterproof IP67 Micro Switch For Motor Control". A catalog sorted by application puts a door lock or motor control position one step from a series name.

Best for: Door lock and motor control positions that take a pre-wired switch.

Where IP67 is stated: The MT8 series page and IP67 product titles.

Strengths

Safety approvals listed on the MT8 series page.

Wire leads and wire type specified per product.

Limitations

Approvals listed for the series, so the part number carrying each one is confirmed per order.

FBelec

An IP67 series offered with or without a lever.

The MAE page is titled "Wholesale Waterproof Micro Switch IP67 Series MAE Microswitch with/without Lever", and FBelec describes itself as "one of the top wholesale as weatherproof switch manufacturers, suppliers, and exporters in China." A page that names wholesale and manufacturing together makes the production site a first-enquiry question.

Honeywell

Sealed basic switches in miniature and subminiature sizes.

MICRO SWITCH is Honeywell's brand for these parts, and its sealed basic switch comparison describes the miniature and subminiature families as "Water-tight. Dust-tight." and "Sealed to IP67." A comparison document across sizes lets switch size be chosen inside IP67.

Best for: A sealed position where the size is still open between miniature and subminiature.

Where IP67 is stated: The sealed basic switch comparison document.

Strengths

Miniature and subminiature sealed families in one comparison.

Water-tight and dust-tight on the same document.

Limitations

IP67 stated across families, so the series is named in the request.

ITW EBA

A sub-miniature IP67 series for automotive, EV charging and industrial positions.

ITW EBA lists its SWA series as "Sub-Miniature IP67 Rated Waterproof Micro Switches" for "automotive, EV charging, and industrial applications with gold-plated contacts", with an operation temperature of -40 to 85°C. A series page that names its applications and its temperature range answers the position and the IP67 together.

Best for: Automotive and EV charging positions that call for gold-plated contacts.

Where IP67 is stated: The SWA series page.

Strengths

Gold-plated contacts.

Operation temperature of -40 to 85°C.

ZINGEAR

IP67 model pages across the automotive, new energy, home appliance and industrial lines.

ZINGEAR micro switches carry Protection Class IP67 on the parameter tables of ZINGEAR G303 in the automotive line, ZINGEAR G10B03 in the new energy line and ZINGEAR G5W11 for home appliance and industrial heavy-duty positions. Huizhou Micro Technology Co., Ltd. is the sole original manufacturer of ZING EAR brand micro switches, and UL is held on ZINGEAR G5W11, with IATF 16949, ENEC, CQC and CB held at company level. Terminal type, lead exit and sealing grade are among the parameters settled during configured micro switch development. Model-level IP67 in three product lines lets a vehicle lock, a charging station lock and a damp appliance position go to one supplier.

Best for: Programs that need model-level IP67 on automotive, new energy and appliance positions from one manufacturer.

Where IP67 is stated: Protection Class IP67 on the model parameter tables.

Strengths

Epoxy potting of the terminal cavity as standard, combined with low-pressure molding over the soldered wire exit on individual soldered-lead models.

Rated from -40°C to +85°C on the automotive line.

IP67 with exclusions or conditions

Kangerle

Sealed series that reach IP67 once wired.

Kangerle builds its waterproof micro switch around "a waterproof silicone sleeve", and its structure page says the switch "will reach IP67-grade waterproof and dust-proof production after wiring". The sealed range runs from the KW1 and KW2 to the WS1 and WS2 high current switches. IP67 tied to wiring makes the wiring step part of what the order specifies.

Best for: Positions supplied as a wired switch.

Where IP67 is stated: The waterproof micro switch structure page, with a wiring condition.

Strengths

Silicone sleeve sealing across the sealed range.

High current sealed series alongside small sealed series.

Omron Components (ARATAS Americas)

An ultra-subminiature switch developed for automotive door latches.

Omron describes the D2EW as "born from automotive applications" with "water resistance (equivalent to IP67)", and the switch "was originally developed for automotive door latches." Equivalent to IP67 is Omron's own wording, so a requirement written as an IP67 rating asks the supplier for a direct yes on the D2EW.

Best for: Door latch positions with little room for the switch.

Where IP67 is stated: The D2EW page, as equivalent to IP67.

Strengths

Ultra-subminiature size aimed at door latches.

Described for uses prone to water and condensation.

Limitations

Water resistance described as an equivalent of IP67.

Unionwell

IP67 on the switch body, with the terminal placed outside.

Unionwell's waterproof product page says the switch is "Designed for water and dust tight(IP67)", and the parameter table on the same page reads "IEC IP67(Terminal not included)". On its subminiature range, "the side/bottom of base from where lead wires come out are well sealed with specially developed glue." A parameter table that places the terminal outside IP67 shows exactly where the rating stops.

Best for: Wire-lead positions where the lead exit is sealed by the supplier.

Where IP67 is stated: The waterproof product page and its parameter table.

Strengths

ENEC/UL and cUL listed for the IP67 switch on the same page.

Subminiature and clip-type subminiature IP67 series.

Limitations

Terminal outside IP67 on the parameter table.

Company-level IP67

Dongnan

IP67 named on the company page, waterproof on the model page.

Dongnan Electronics, established in 1987, welcomes visitors to "the world of high-quality IP67 micro switches", and its WS1 page, a vacuum cleaner switch, is titled "Waterproof Micro Switch". Company-level IP67 makes the model the first question: which WS1 part number carries IP67.

Best for: Appliance positions such as vacuum cleaners.

Where IP67 is stated: The company page.

Strengths

Switch manufacturing since 1987.

WS1 waterproof series for appliances.

Limitations

IP67 confirmed per model.

Starting points by application: vehicle locks, EV charging, appliances and industrial equipment

An application is the second filter after the group, and each supplier's pages name the positions its sealed series serve. A supplier whose IP67 series already names your position is the quicker route to a sample.

• Vehicle locks and door latches: ZINGEAR G303 for door locks, tailgate locks and charging port covers, Omron D2EW for door latches, Donghai door lock switches and ITW EBA SWA for automotive positions.
• EV charging: ZINGEAR G10B03 for locking detection in charging systems, ZINGEAR G306A for charging gun insertion detection with the resistor inside the switch, and ITW EBA SWA for EV charging.
• Home appliances: ZINGEAR G5W11 for long-term damp exposure and Dongnan WS1 for vacuum cleaners.
• Industrial equipment: ZINGEAR G5W11 in the industrial heavy-duty line, Donghai motor control switches and ITW EBA SWA for industrial positions.

Named programs show where ZINGEAR parts already run these positions, with vehicle programs under automotive industry solutions and appliance programs under household appliance solutions.

Terminal coverage, the electrical rating and the full part number are settled before a sample order

The sample is where the switch first meets your position, with the terminals wired your way and the vibration and corrosion covered in IP67 beyond moisture and dust.

On a ZINGEAR part proposed for your position, the ZINGEAR engineering team answers the terminal question directly, naming IP67 coverage of the terminals and the lead exit against the full part number before samples ship.

Once a sample passes, the project moves on to testing and mass production, and our guide to micro switch suppliers that support selection, samples, testing and mass production follows those stages.

FAQ About IP67 Micro Switch Suppliers

Does an IP67 rating on a micro switch include the terminals?

Each supplier's page answers it differently, and the record that decides it for a given part is the IP67 test itself. A test run on the switch with its leads attached covers the terminal end; a test on the bare switch covers the body. Asking which of the two was run settles the terminal question for that part.

Is "equivalent to IP67" the same as an IP67 rating?

Equivalent to IP67 is a supplier's own description of water resistance. The question that resolves it is which test the description rests on, since a part tested to the IEC 60529 procedure for IP67 can be stated with the rating itself.

Does an IP67 micro switch also need a safety approval?

The switch needs whichever approval the end product's market asks for: UL and cUL for North American end products, ENEC for Europe and CQC for China. IP67 travels with the switch into every one of those markets, and the approval list changes with each.

Is MICRO SWITCH a brand or a type of switch?

MICRO SWITCH in capitals is Honeywell's brand name for its snap-action switches, and micro switch in lower case is the general name for the snap-action type that every supplier in this article builds.
