Capacitive contact switch, particularly for domestic electrical appliances

摘要

On the dielectric switch panel, a capacitor-type area element is arranged in the approach or contact area, which is arranged in the circuit on the control path between a resistor, following an oscillator circuit, and an evaluating circuit; the capacitor area, together with the approaching or applied switching body (finger), and the resistor following the oscillator circuit acts as low-pass circuit for the frequency generated by the oscillator circuit. <IMAGE>
