SW-520D Vibration Sensor Metal Ball Tilt Switch (Pack of 2)

The SW-520D Vibration Sensor Metal Ball Tilt Switch (Pack of 2) is a simple yet effective motion detection component used to sense tilt, vibration, or basic orientation changes. Unlike complex accelerometers, this sensor uses a metal ball inside the cylindrical housing that moves and makes contact with conductive poles when tilted or shaken, thereby closing the circuit.

Encased in shrink tubing for insulation and durability, the SW-520D is perfect for hobby electronics, embedded systems, and low-power motion-triggered applications. It offers a basic ON/OFF signal that can be read directly by microcontrollers like Arduino and Raspberry Pi, making it ideal for alarms, tilt detection, and simple motion sensors.
