A contact switch for lamps, characterized by the use of an electronic circuit, interposed at one of the poles of the network, whose circuit is part of an electrode sensitive to a parasitic capacitance located opposite it, as well as two resistors, with a capacitor, a voltage divider and a thyristor, through a "gate" occurs the transformation of the parasitic current, to produce a movement in a step-by-step relay; the impulse transmitted by the thyristor to its coil gives rise to a position of its contacts, be it work or rest, which is maintained indefinitely even in a new impulse of the same parasitic origin, giving rise to the position variation of the contacts of the relay, closing or opening the electrical circuit of the network and turning on or off the lamp.
