摘要： The invention relates to a contactless safety switch for detecting the shut position of a shutting part in relation to a closeable part, with a switch unit, supplied with current by an electrical supply source on one of the parts and with a trip arranged on the other part and comprising a magnet. In this case, the switch unit comprises a transmission circuit with a clock-signal generator and with a transmission coil, a receiver circuit connected to an evaluation unit and having at least one receiver coil and also a Hall sensor responding to the magnet, and the trip comprises a trip coil which is capable, in the shut position, of being excited inductively by the transmission coil and exciting the receiver coil, while, in the shut position, the evaluation unit triggers a clearance path when the Hall sensor is activated via the magnet.

摘要： A novel construction for a multifunctional rotary switching device is provided. The body of the switch includes a radial array of magnetic field effect sensors arranged on a base switch component such as a printed circuit board switching substrate. Each of the sensors is connected via circuit traces with a central logic chip also mounted on the circuit board. An array magnets is installed into a rotatable actuator in close proximity to the surface of the sensors whereby the magnetic force causes the corresponding sensors to switch to an open position when one of the magnets is in their proximity. In this position, the logic chip can detect which of the sensors are open and execute a set of pre-programmed instructions corresponding to the sequence of open sensors.
