HOMEContactless touch switches
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.
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.
