Contactless touch switches

Features

・Long lasting, stable operation in repeated use, ensured by contactless circuit.
・Very high precision in operating point repeatability.
・Environment resistance achieved by the configuration separating the moving part from the sensing part.
・Can be customized to a limited operational force spec.
Features

Mechanism

An external input pushing or pulling the probe moves the magnet back or forth, respectively. By sensing the magnet's movements and then inducing ON/OFF actions, the magnetic sensing circuit serves as a touch sensor. Since the sensor reacts at steep slopes of magnetic gradient, highly sensitive and precise repeatability is provided for operating points. Mechanism
