Description
These SW-420 Normally Closed Vibration Sensor Switches are compact, sensitive, and ideal for detecting mechanical vibrations, shaking, or tilting in your electronic projects.
Housed in a sealed moisture-proof and dust-proof shell, these switches respond to motion by briefly changing state, making them perfect for anti-theft alarms, motion detectors, or tilt-based triggers.
