Electric Vehicles (EVs) Switch

Introduction to Electric Vehicles Micro Switches

Micro switches are key components in electric vehicle and new energy vehicle charging systems, widely used in charging gun interfaces and locking structures. Their function is to detect mechanical position or operational status and quickly convert these changes into electrical signals, ensuring the safety and reliability of the charging process.

Features of Unionwell Electric Vehicle Micro Switches

1. Employs a fast-acting contact structure, achieving rapid switching through the instantaneous flipping of an internal spring, reducing contact bounce and malfunctions.

2. Offers long lifespan and high stability, enabling reliable long-term operation in frequent use and complex environments.

3. Features waterproof and dustproof capabilities; the sealed housing and structural protection ensure stable operation in harsh environments.

4. Offers customization capabilities; different sizes, terminal types, and actuator structures can be manufactured.

Application Case

Application of Electric Vehicle Micro Switches in EV Charging Guns

These micro switches are mainly used in the locking structure of the charging gun and the position of the charging port locking pin in automotive charging guns.

They are primarily used to detect:
Whether the charging gun is fully inserted;
Whether the locking structure is locked/unlocked;
Whether the user is preparing to remove the charging gun while it is powered on.

Applications of Electric Vehicle Micro Switches in Door Locks

These micro switches may also be used inside door lock actuators, door latches, or at the tongue's travel end.

They are primarily used to detect whether the door is fully closed, whether the door lock is locked/unlocked, and to provide specific signals to the central locking and body control modules.

Applications of Electric Vehicle Micro Switches in Seat Adjustment

Some of these micro switches are also used at the ends of seat rails.

They are mainly used to detect the seat position and whether it has reached its limit position, thereby improving the overall safety and durability of the seat.
