Tilt switches are motion sensors designed to detect changes in orientation or inclination of objects with respect to gravity. These sensors contain a conductive metal ball or mercury switch suspended within a housing. When the switch tilts beyond a certain angle, the metal ball completes an electrical circuit, signaling a change in position. Tilt switches are commonly used in safety devices, alarm systems, and industrial equipment for applications such as tilt detection, level sensing, and anti-tipping mechanisms. They offer simple, reliable, and cost-effective solutions for detecting motion or position changes in various environments, contributing to improved safety and functionality in electronic systems.
