SW-520D Mercury Tilt Switch Module مستشعر الميل

The SW-520D Mercury Tilt Switch Module مستشعر الميل provides precise tilt detection using a sealed mercury-based sensor for reliable electrical switching. This compact module is designed for applications requiring accurate inclination sensing with minimal power consumption.

• Activation angle: approximately 10 degrees for responsive tilt detection.
• Operating voltage: DC 3V to 24V, compatible with most microcontrollers and circuits.
• Low current draw: 20mA to extend battery life in portable devices.
• Compact size: 30mm x 10mm for easy integration into confined spaces.
• Durable construction: reliable performance over thousands of tilt cycles.

Compared with typical mechanical tilt switches, the SW-520D offers greater signal stability and reduced contact noise due to its mercury contact design. The sealed mercury switch closes or opens the circuit based on tilt angle, which minimizes contact wear and helps maintain consistent electrical conductivity over time. Its sensitivity threshold near 10 degrees and wide operating voltage range make the module suitable for both hobbyist and professional applications.

Common uses include robotics, alarm and safety systems, simple orientation detection, and other control applications where compact size, low power consumption, and reliable tilt switching are required.
