SW-18020P Vibration Sensor – Spring Type Shock Detection Switch

The SW-18020P Vibration Sensor is a compact, spring-type mechanical vibration switch designed to detect vibrations, shocks, and sudden movements in electronic circuits. Featuring a normally open contact mechanism, the sensor responds to external mechanical disturbances by momentarily closing its internal contacts, enabling simple and effective vibration detection.

The sensor features a sealed cylindrical housing with two connection terminals, providing dependable switching operation in low-current electronic applications. Its omnidirectional sensing mechanism allows vibration detection from different angles without requiring a fixed orientation.

The SW-18020P Vibration Sensor is suitable for anti-theft alarm systems, smart home devices, automotive electronics, electronic toys, and microcontroller-based projects. Its compact design and simple two-pin interface make it convenient to integrate into electronic circuits requiring motion-triggered switching.
