Abstract: The invention relates to an inductive sensor unit having one or several coils, which are mounted on a printed circuit board in a planar manner. According to the invention, a change in the inductance of a sensor coil due to leakage currents in the inductive actuator is correlated with the position of the actuator in two respects i.e., with the distance x to the sensor coils and with the overlapping y of the sensor coils. As a result, an inductive push button switch and an inductive position switching device (a sliding switch) are provided. The invention also relates to the evaluation of the inductance by means of reactance measurement.

Abstract: An electrical switch has a common contact body and a first selective contact body and a second selective contact body. A contactor is connected mechanically and in an electrically conducting manner to the common contact body. The contactor comprises an elastic, electrically conducting material. It is formed originating from the basic form of a leaf spring into a multifunctional part having a clamping area, a deformation area and a stiffened actuating area. The pre-tension of the contactor causes the contact fingers to be positioned against the contact surfaces of the first selective contact body. Pressure on the actuating area elastically deforms the contactor, and the actuating area pivots with the contact fingers so that the contact fingers switchingly enclose the contact surfaces of the second selective contact body.
