Reliable Micro Switches for EV Charging Stations

Addressing the stringent safety and durability requirements of electric vehicle charging stations, Unionwell Micro Switches feature an IP67 waterproof rating, enabling stable operation in complex outdoor environments such as humid and dusty conditions.

For example, the subminiature micro switch operates within a temperature range of -40°C to +85°C and a maximum operating humidity of 85%RH, adapting to harsh climatic conditions. It also boasts an insulation resistance of ≥100MΩ (500VDC), ensuring electrical safety and stability. With an electrical life of 10,000 cycles and a mechanical life of up to 1,000,000 cycles, it is widely used in charging gun connection detection and safety interlock systems, making it a reliable core component in EV charging systems.

Extra-Long Lifespan: Rigorously tested for lifespan, capable of withstanding hundreds of thousands of mechanical operations, meeting long-term operational needs.

Applications of Microswitches in
Electric Vehicle Charging

In new energy vehicle charging gun systems, the G23 motor electronic lock switch is integrated into the charging gun control structure, participating in the entire charging safety closed loop. Its specific application process is as follows:

1. Insertion Detection: When the charging plug is inserted, the G23 micro switch quickly responds to displacement changes and sends an insertion signal back to the control system.

2. Signal Trigger: After receiving the switch signal, the control board drives the motor electronic lock to activate, entering a locking preparation state.

3. Mechanical Locking: After the electronic lock completes its action, the micro switch synchronously confirms the locking position, ensuring the plug is reliably fixed.

4. Safe Charging: After the locking state is confirmed, the system allows power to be supplied. The micro switch continuously provides status monitoring to ensure stable charging.

5. Unlocking and Release: After charging is completed, the lock is released via a control signal, and the micro switch sends an unlocking status feedback, allowing the plug to be safely removed.
