Product Description
 
The Dual-circuit Car Sealed Subminiature Micro Switch G307A Series is a subminiature micro switch specifically designed for automotive handbrakes. Its dual-circuit structure enables precise handbrake position detection. Its compact size makes it suitable for confined installation spaces while maintaining stable operation.

As an automotive micro switch, it provides reliable signal feedback within the handbrake mechanism, allowing the vehicle to accurately identify the handbrake's engagement or disengagement. The product boasts an operating temperature range of -40℃ to +85℃, a mechanical lifespan of 500,000 cycles, and an electrical lifespan of 300,000 cycles, maintaining consistent performance even under prolonged and frequent operation.

This product is also a sealed micro switch with an IP67 waterproof and dustproof rating, ensuring stable operation in environments with high humidity, rain, and mud. Designed meticulously by the micro switch manufacturer, this product guarantees a balance of reliability, safety, and durability.
