ABSTRACT:
A touch control switch suitable for connection between a lamp load and a supply circuit in a lighting installation for alternating current and comprising a semiconductor switching element with a gate electrode, a counting circuit with a forward stepping input and a digital control output connected to the gate electrode of the semiconductor switching element via a trigger pulse generating circuit for controlling the conduction of the semiconductor switching element in dependence on the condition of activation of the digital control output, and a control pulse shaping circuit having an output connected to the forward stepping input of the counting circuit and a first and second input terminal for connection respectively to a first and second terminal of the supply circuit via a touch sensitive impedance. The control pulse shaping circuit comprises a clipper stage with a clipping level controlled by a first voltage-level detector circuit. In the clipper stage, a second voltage-level detector circuit is included with a higher clipping level than the clipping level controlled by the first voltage-level detector circuit and with an input and output connected to the input and output respectively of the clipper stage.
