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.

Abstract: A motion-restraint arrangement (48) with elongate lines of elements (10), wherein each line of elements (10) has a number of individual elements (12) which can be erected by spring elements (20) from a small-volume thin storage condition into a large-volume active condition. Each respective individual element (12) has flexible lateral edge elements (16, 18), which in the active condition define a parallelepiped. The spring elements (20) extend in spatially diagonal relationship between the corners (22) of the respective parallelepiped (14). A motion-restraint arrangement (48) which is easy and inexpensive to produce and which has optimum restraint properties is obtained in that the spatially diagonal spring elements (20) are formed by spring wires (24), which extend in a zigzag shape in the longitudinal direction of the respective line of elements (10).
