Electrical Life: 10,000 to 50,000 cycles (depending on load conditions)

Actuator Types

G10B03-150P00A: No lever (button type), suitable for new energy vehicle smart locks

G10B03-150P03A: Straight lever, suitable for EV charging guns

G10B03-150P04A: Bent lever, suitable for EV charging stations

Choosing the appropriate actuator type directly affects the switch’s durability and performance.

2、Required Installation Tools

For safe installation of G10B micro switches, prepare:

Precision screwdriver set

Soldering iron (if terminals need soldering)

Multimeter (to test continuity)

Screws matching the mounting holes

Having all tools ready simplifies the installation process and prevents damage to the switch.

3、Installation Steps

Determine installation location: Ensure there is enough space around the actuator.

Mark mounting points: Align according to the official drawing hole dimensions.

Secure the switch: Insert screws into the mounting holes and tighten gently to avoid cracking the plastic housing.

Connect electrical terminals: Solder or use plug-in connectors, distinguishing COM, NO, and NC.

Test functionality: Use a multimeter to confirm proper switch operation (COM-NC closed when unpressed, COM-NO closed when pressed).

Following these steps ensures the switch operates reliably in your application.

4、Common Errors and Solutions

Paying attention to these issues prevents damage and extends switch life.

5、Tips for Extending Switch Lifespan

Keep the switch clean and free from dust and debris

Avoid excessive force on the actuator

Confirm electrical load matches rated specifications

Periodically check contact resistance (replace if >200 mΩ)

These practices help maintain stable performance and prevent premature failure.

6、Conclusion

The G10B micro switch is a reliable component for precise mechanical and electrical control. Understanding its dimensions, installation process, and common issues allows beginners to confidently integrate it into projects. Using proper tools, careful installation, and adhering to rated electrical parameters ensures safe, stable, and long-lasting operation.
