This vibration switch alarm sensor is designed to detect movement, tilting, or vibration in electronic circuits. It is commonly used in small household appliances, motorcycles, alarms, anti-theft systems, smart cars, and other projects that require motion-triggered switches to activate circuits or security systems.
You will get 24 Pcs x Vibration Switch; Model Number: SW-420; Voltage: 12V; Rated Thermal Current: 20mA; Insulation Resistance: 10M ohm; Temperature Resisting: -40-80℃; Body Size: 9 x 5mm / 0.35 x 0.2 inch(L*D)
This curved pin sensor switch is made of excellent metal and features stable operating voltage, waterproof and moisture-proof properties, and a long service life. Compared to traditional buzzer structures, the SW-420 sensor primarily senses vibration through a roller, resulting in a simpler and more durable structure. The vibration sensor can detect vibrations or tilts in different directions with high sensitivity.
Solder the sensor pins into the circuit according to your circuit diagram, oriented as required. The switch is normally in the open state and will temporarily close when sufficient vibration or tilt is detected. Test the sensor response before use to confirm its trigger sensitivity.
This product is a low-current switch and is not suitable for directly controlling high-power devices. This switch is sensitive to physical shock; handle with care during installation.
