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. A relative evaluation of the influence of adjacent sensor coils increases the precision of response in push button switches and, generally, a relative evaluation of the influence of adjacent sensor coils is carried out in position switching devices.

Abstract: The invention relates to an inductive sensor unit having one or more sensor coils, which have been mounted on a printed circuit board in a planar manner. According to the invention, a change in the inductance of the sensor coils caused by leakage currents in the conductive actuator is correlated with the position of the actuator with regard to the distance from the sensor coil and with the overlapping of the sensor (at a fixed distance). This provides the basis for an inductive momentary contact switch and an inductive position switching device. The invention also relates to the evaluation of the inductance, e.g. of the momentary contact switch such as in inductive proximity switches by incorporating the inductive sensors in an oscillating circuit. Alternatively, the change in inductance can also be detected by a reactance measurement. A relative evaluation of the influence of adjacent sensor coils is carried out in position switching devices.

Abstract: In an arrangement for limiting the temperature of a glass-ceramic cooking zone including a cooking zone control unit which controls the electric power supply to the heating elements of the cooking zones by way of an impulse width control arrangement with a cycling relay, an additional module with a signal processing unit is provided with temperature sensors for sensing the cooking zone temperatures so as to provide temperature signals to an evaluation circuit which compares the temperature values with a maximum temperature value and keeps the cycling relay in an open position when the temperature values reach the maximum temperature to thereby interrupt the power supply to the heating elements and the signal processing unit and opens a main power supply if the temperature still rises after having reached the maximum value.
