With highly developed electronic instruments abounding and an avalanche of information being communicated these days, the need for sensors is increasing. Sensors are needed, among others, in the place where safety or security is prerequisite and for systems where they are needed to attain particular purposes required for each system. We developed a Tilt Switch using Magnetic Fluid. It detects an angle of tilt with high accuracy and reliability. Conventional tilt switches were mainly a mercury applied type or a mechanical type. This Tilt Switch is made possible by magnetic ally levitating using the metallic magnetic fluid developed by our own technology. The movement and tilt of the levitated metallic magnetic fluid provides a switching function.Our metallic magnetic fluid has excellent characteristics. It has high flux density resulting in strong magnetic levitation and its flux tends to be concentrated making it possible to detect tilt angle with high sensitivity and accuracy.
