ABSTRACT:
A touch operated electronic switch for alternating current including a full wave rectifying bridge and two unidirectional current electronic switches one being mounted in parallel with said bridge input and the other being mounted in parallel with said bridge output, each unidirectional current electronic switch being such a silicon controlled rectifier which can be triggered by a touch plate. Said bridge input poles are the two external connections of said A.C. switch. Said unidirectional current electronic switch inserted between said bridge output poles is combined with a low inertia accumulator of electrical energy such as a capacitor mounted in parallel or an inductance mounted in series therewith. A device comprising a neon indicator and its dropping resistor is mounted in parallel with said bridge input so as to faintly light in transparency the touch operated electronic switch for A.C. when it is turned off. Any such touch operated electronic switch for alternating current acts as a multiple-way switch of a load when it is mounted in parallel with any number of same switches by said bridge input on the only two leads which conduct one to the load and the other to an A.C. potential source.
