Abstract: An electrical switch includes a rotary switch actuator device, and an actuator locking device. The actuator locking device inhibits the rotation of the rotary switch actuator device when the contacts of the switch are closed. Only when the operator tries to open the switch with an operating handle and the contacts do actually open, a lock release device will release the actuator locking device, and allow the operator to move the operator handle to the position corresponding to the open condition. When the contacts do not open, e.g., because they are welded, the actuator locking device will remain locked and the handle movement is blocked. This provides a robust and safe switch that never gives a false “OFF” indication.

Abstract: A device with a key-actuated closing cylinder and a switch triggers, when a key is turned therein, a particular electric function in a motor vehicle. In order to achieve a particularly compact and reliable device, at least two sensors are arranged inside the cylinder housing of the closing cylinder in zones that are mutually offset in the longitudinal direction. The sensor outputs are connected to a common evaluation device. The cylinder core has in corresponding axial zones several permanent magnets at particular points of its periphery. These points are selected so that the evaluation device detects different codes at the sensor outputs in the different working positions of the cylinder core and clearly identifies with these codes the corresponding working positions. The evaluation device thus acts as an electronic switch which on the basis of the sensed code triggers the electric function that corresponds to the momentary working position.
