Features

• Detects vibration, shock, and tilt
• Model: SW-420 (normally closed switch)
• Adjustable sensitivity via potentiometer
• Digital output (High/Low)
• Operating voltage: 3.3V to 5V
• LED indicators: Power & Output
• Compact size with mounting hole
• Fast response time
• Low power consumption
• Ideal for security alarms and robotics
• The SW-420 Vibration/Shock Sensor Module uses a spring-based switch that closes when subjected to vibration, shock, or tilt. It acts as a normally closed switch—output goes LOW (0V) when triggered.
• Sensitivity is adjustable via the onboard potentiometer. Two LEDs indicate power status and trigger events.
• Perfect for burglar alarms, earthquake detectors, vehicle security, and robotic fall detection. Simple digital interface makes it easy to use with Arduino and other MCUs.
