"Top Micro Switch Suppliers in 2026: Sorted by Switch Type, With the Company Behind Each Brand"

A micro switch sourced before the application is settled usually starts from supplier names known for high quality, long life and reliable snap-action performance. Which type of switch does each supplier make, and which company and factory stand behind the brand on the part? A supplier name is ready for a shortlist once the name is matched to the switch types its published range covers by size, sealing and load, and to the company and factory that make the switches sold under the brand. Supplier ranges are sorted by switch type and tied to the company behind each brand, so purchasing managers can build a shortlist that matches the part they need.

Size, Sealing and Load: The Three Axes That Place a Micro Switch

A micro switch datasheet states a size class, a sealing version and a load rating for the same part, and each of the three is chosen on its own. A subminiature switch can come sealed or open and be rated for a signal or a motor load, so your position picks one value on each axis before any supplier enters the comparison.

Size class

Size class names come from each maker's own catalog, so the outline drawing is what settles fit between two makers. The suppliers in this list use names that run from basic and standard through miniature, subminiature, ultra-miniature and sub-subminiature. Across two catalogs, the body dimensions and mounting-hole spacing on each outline drawing carry the comparison.

Sealed or unsealed

Sealing is published version by version, so a sealing rating belongs to the part number that carries it. Several ranges below offer one series in sealed and unsealed versions, and the IP67 rating defined in IEC 60529 sometimes comes with a stated exclusion, such as the terminals on terminal models. On such a terminal model, the terminals are sealed by your own housing or harness, as compared in how suppliers state IP67 by version.

Signal-level or power-level load

A current rating compares only at the voltage published beside it, and your position decides which end of a range matters. One catalog can hold a 0.1A part at 30VDC for a lock or lid signal and a 16A part at 250VAC for an appliance load, and a figure quoted without its voltage can belong to either.

Which Switch Types Each Supplier Publishes

Eleven ranges, from C&K to ZINGEAR in alphabetical order, cover different cells on the three axes, each described in the words and figures of its own maker. A supplier whose range covers the size class, the sealing version and the load your position needs is a candidate for your shortlist.

Supplier by Supplier: The Company, the Factory and the Published Range

A quotation, an audit notice and a certificate carry the name of a company and the address of a factory, and the brand printed on the switch can differ from both. Matching the company on the quote to the factory on the audit keeps one supplier from being counted twice on your shortlist. A ready-made Top 10 list of micro switch makers is read the same way, starting with the company whose website publishes it.

ZINGEAR

Huizhou Micro Technology Co., Ltd. is the sole original manufacturer of ZING EAR brand micro switches, made mainly in Huizhou. One company and one factory region stand behind every ZINGEAR part number, so the shortlist counts ZINGEAR once. The range runs from ZINGEAR G303 at 0.1A to 3A on the IATF 16949 certified automotive micro switch line to ZINGEAR G5T16-E1Z200 at 16A and 250VAC.

C&K (Littelfuse)

Littelfuse states that its switch line "now includes C&K® switches", so a C&K snap switch is quoted, documented and recorded under Littelfuse.

Crouzet

Crouzet's certification list names sites in Valence and Huizhou, including "IATF 16949 – Huizhou", so the site named on the quote is the site to audit.

DONGNAN

Dongnan Electronics Co., Ltd., in the Yueqing Economic Development Zone, Zhejiang, publishes on switch-china.com and dongnanswitches.com, so a quote from either site counts as one supplier.

Honeywell (MICRO SWITCH)

MICRO SWITCH is a Honeywell brand, so a part marked MICRO SWITCH is quoted, certified and recorded under Honeywell International Inc.

Johnson Electric (Saia, Burgess)

Johnson Electric sells microswitches under the Saia and Burgess brands, so one supplier approval covers parts under either name.

Omron (Aratas)

Omron's electronic components business rebranded as Aratas in July 2026, so an Omron part number on an existing drawing now arrives on documents in the Aratas name.

Panasonic

Panasonic Industry Co., Ltd. splits its micro switches into a seal type family rated IP67 and a non-seal type family, so the sealing choice opens a Panasonic selection.

TONELUCK

TONELUCK products are sold through Shenzhen Greater Electronics Co., Ltd. and made at a manufacturing base in Huizhou, so a quote from the sales company leads to the Huizhou base for audit.

Unionwell

Unionwell names Huizhou Unionwell as headquarters and Huizhou Greetech as its production base, so a Greetech order stays inside the same group as a Unionwell approval.

ZF (Cherry)

ZF Friedrichshafen AG publishes the Cherry microswitch range with an Auerbach, Germany address, so supplier records for a Cherry part name ZF.

Where to Read Next: By Application and by Buying Question

Once your application is set, the comparison to open next is the one written for an appliance, automotive or industrial position. An application comparison measures the same suppliers on what that industry buys on, such as cycle count for appliances or certification for vehicles.

Appliance

Keeping one part the same over long production runs is covered in sourcing appliance micro switches. Doors and lids that operate many times a day are in high-cycle appliance micro switches.

Automotive

Certification, sealing and lead time share one table in certification, sealing and lead-time comparison of automotive makers, and the routes to each supplier are in the channels that supply automotive micro switches. Once a part is fixed on a program, what a design change costs on an automotive program compares how suppliers handle a revision.

Industrial

Suppliers expected to cover industrial, appliance, automotive and new energy work are compared in micro switch makers compared across four industries.

A buying question that cuts across applications has its own comparison:

• Distributor or factory: small replacement buys versus volume orders
• Delivery time: how Chinese suppliers' lead times are built
• New energy and charging: new-energy micro switch suppliers by position and EV charging micro switch suppliers
• Test records before approval: suppliers that run life and waterproof tests in house
• Sample to volume: support from selection to mass production
• Resistor inside the switch: built-in resistor micro switch makers

FAQ About Micro Switch Suppliers and the Companies Behind Them

Why can one brand appear under two company names on a quote?

A group can quote through its headquarters, its production base or a sales branch, each in its own name, as the Unionwell and TONELUCK entries above show. The shortlist still counts that group once.

Does a certificate follow the brand or the factory?

A management system certificate such as IATF 16949 is issued to a company for a named site, and that site is matched against the factory on the quote and the audit plan.

Which type of micro switch should I start with?

Your position sets it, with the space setting the size class, water or dust the sealing version and the circuit the load. Start with a supplier whose range covers all three cells.

Are mouse and keyboard micro switches on this list?

The list in this article covers snap-action micro switches for appliances, vehicles and industrial equipment. Mouse and keyboard switches, tactile switches and push button switches are compared by the makers and distributors that catalog them.

How can I tell whether a supplier has run a position like mine before?

Ask for a named application on the supplier's own pages, with the part number that served it, which shows the same switch has already been built for a comparable position.
