Tilt Switches
Products in the tilt switch family are designed to provide a binary (two-state) indication of whether or not their orientation with respect to gravity is in excess of some specified angular value. Commonly, though not exclusively, based on a passive mechanism of action such as the motion of a conductive element under the influence of gravity, such sensors can operate without need of an external power source in applications where inclination threshold detection is sufficient, as contrasted with inclination magnitude measurement.
