   5. Key Selection Parameters

（1）Contact Type

SPDT (Single Pole Double Throw): Provides both normally open and normally closed signals, suitable for status detection and feedback.

SPST-NC (Single Pole Single Throw - Normally Closed): Normally closed contact, opens when pressed, suitable for safety or alarm circuits.

（2）Operating Force

180g: Clear tactile feedback, prevents false triggering, suitable for automotive and outdoor use.

Customizable: Can be adjusted according to mechanical structure for flexible application.

（3）Protection Level

IP67: Fully dustproof, short-term immersion in water (up to 1m depth, 30 minutes).

Note: Not suitable for long-term submersion. Ensure seals and wire connectors are intact during installation.

（4）Lifespan Reference

G303 Series: Mechanical life ≥500,000 cycles, electrical life ≥100,000 cycles. Approximately 13+ years at 100 daily operations.

G306 Series: Mechanical life ≥300,000 cycles, electrical life ≥300,000 cycles. Approximately 8+ years at 100 daily operations.

Actual lifespan may vary depending on load type, environmental temperature, and operation frequency.

6. FAQ

Q1: What is the difference between SPDT and SPST-NC?

SPDT: Provides normally open + normally closed contacts, suitable for status detection

SPST-NC: Normally closed contact, opens when pressed, suitable for safety or alarm circuits

Q2: How to choose the operating force of a micro switch?

180g: Clear tactile feedback, prevents false triggering

Customizable: Can be adjusted according to mechanical structure

Q3: Can IP67 waterproof micro switches be submerged long-term?

No. IP67 only guarantees short-term immersion. Ensure seals and connectors are intact.

Q4: How long will a G3 micro switch last?

G303 Series: About 13+ years at 100 operations per day

G306 Series: About 8+ years at 100 operations per day
