Description:
SW-520D Tilt Switch Vibration Sensor Metal Ball Tilt Sensor is a compact and reliable mechanical sensor designed for detecting tilt, inclination, shaking, vibration, and position changes. Unlike complex accelerometers that require signal processing and programming, this simple tilt switch works as an electrical ON/OFF contact based on its physical orientation, making it an easy solution for basic motion and position detection applications.
The SW-520D uses an internal metal ball mechanism that changes the switch state when the sensor is tilted to the appropriate angle. When the sensor is positioned correctly, the conductive ball makes contact with the internal terminals, allowing the circuit to turn ON. This straightforward operating principle makes the SW-520D vibration sensor suitable for Arduino projects, robotics, electronic circuits, alarm systems, safety devices, and industrial automation applications.
With a maximum operating voltage of 12V and maximum current rating of 20mA, the sensor can be integrated into low-power electronic circuits and control systems. Its compact construction allows convenient installation in space-constrained projects. The protective shrink tubing helps provide insulation around the sensor and terminals, reducing the risk of accidental short circuits during integration.
The SW-520D tilt switch sensor is also designed for reliable operation in applications requiring orientation or position detection. It can be used to detect whether equipment has been tilted, moved, shaken, or positioned beyond a specific orientation. This makes it useful for DIY electronics, robotics, security systems, equipment monitoring, and other projects requiring a simple mechanical tilt detection solution.
Whether you are developing an Arduino tilt sensor project, robotic system, vibration alarm, or industrial monitoring circuit, the SW-520D provides a practical and economical method for detecting changes in physical orientation.

Frequently Asked Questions ( FAQs )
1. What is the SW-520D Tilt Switch?
The SW-520D is a mechanical metal ball tilt and vibration sensor that detects changes in orientation. When tilted to a suitable angle, the internal metal ball moves and changes the electrical state of the switch.
2. How does the SW-520D work?
The sensor contains a conductive metal ball inside its housing. When the sensor is tilted, the ball moves and makes or breaks contact with the internal terminals, providing a simple ON/OFF output.
3. Is the SW-520D normally open or normally closed?
The switching state depends on the physical orientation of the sensor. In the recommended resting position, it remains OFF and changes state when tilted sufficiently.
4. Can I use the SW-520D with Arduino?
Yes. The SW-520D can be used with Arduino and other microcontroller boards as a simple digital tilt or vibration input. The sensor should be connected according to the selected circuit configuration.
5. Can this sensor detect vibration?
Yes. The SW-520D can detect certain shaking and vibration movements because movement of the internal metal ball changes the electrical contact.
