Abstract

Improvements in the construction of electronic contact switches for mounting in installation systems with one input conductor and one output conductor, consisting of a monostable tilting degree with subsequent bistable tilting degree and subsequent tripping circuit for the power thyristor, acting as switch for the switching of a consumer, characterized in that, when touching a touch surface, a small current derived from the phase flows through a thyristor tetrode or a single junction programmable transistor or a thyristor of an ohmic value resistance high, as well as across the touch surface and the resistance of the user's body to ground, where the thyristor tetrode or single junction programmable transistor or thyristor releases a current pulse which, at a working resistor, generates a voltage impulse which, in turn, causes a change in the bistable tilting degree state, which initiates the maneuver of a field effect transistor, in which the tripping circuit of the power thyristor is included in such a way that the power thyristor connects or disconnects the consumer according to the previous state.
