Abstract: An actuator for the power control of at least one connected load has a load detection device for detecting a magnitude of a load and/or a type of a load of the at least one as a measurement variable relating to the load of the at least one consumer. A communication interface receives at least one manipulated variable for the power control of the at least one consumer and transmits the measurement variable detected by the load detection device.

Abstract: An AC voltage controller has two transistors which can be positioned between two AC voltage terminals in series with a load. The two transistors are connected in series in such a way that their respective source terminals are connected to one another. The AC voltage controller also contains a signal generator for generating a switching signal for actuating the two transistors, a buffer which is connected downstream of the signal generator and which is set by the signal generator in order to actuate the two transistors. An actuation circuit or driver circuit is connected downstream of the buffer, for the purpose of actuating the two transistors in accordance with the set state of the buffer. A current-limiting circuit is provided for limiting or switching off the current through the two transistors in the case of an excessively large current through the load.

Abstract: An operator control panel for a domestic appliance includes a panel body having an operator control face facing a user and a rear face facing away from the operator control face. A sensor element of an electrically conductive material forms a capacitive sensor area together with the panel body. A conversion electronics system converts capacitance values generated in the sensor area into digital signals. The conversion electronics system is electrically conductively connected to the sensor element and is disposed on the rear face of the panel body. The sensor element and the conversion electronics system are firmly connected to the panel body and are two components which are mechanically decoupled from a control electronics system of the domestic appliance.

Abstract: A rotary selector forms a control element for inputting a setting value to an electronic control system, in particular for a control device of an electronic domestic appliance, such as a washing machine, a dishwasher, or the like. The rotary selector has a rotatably mounted control portion and an adapter non-rotatably connected to the control portion. The adapter has a latching section with side faces arranged uniformly about its periphery. Coaxially with the latching section of the adapter is a stationary spring element formed with elastic legs arranged uniformly about a periphery of the latching section and which extend tangentially relative to the side faces of the latching section. The number of the side faces of the latching section is an integral multiple of the number of the elastic legs of the spring element.

Abstract: A circuit configuration for a capacitive touch switch contains at least one sensor circuit with a capacitive sensor element which changes its capacitance value when touched, and an evaluation circuit which is supplied with an output signal from the sensor circuit in order to determine whether the capacitive sensor element is actuated or not. The at least one sensor circuit has a capacitance which is connected in parallel with the capacitive sensor element, and a capacitance/frequency converter which is connected to the parallel circuit containing the capacitance and the capacitive sensor element and generates, at its output, a frequency signal whose frequency depends on the total capacitance of the parallel circuit containing the capacitance and the capacitive sensor element. The evaluation circuit may thus use a significant change in the frequency of the output signal from the sensor circuit to deduce, in a simple manner, that the capacitive sensor element has been touched.
