Circuit is shown, which includes zero-drive switch, the optical coupler type input circuit, a control circuit and the thyristor circuit audible sound. FIG phototransistor switch circuit connected to the inverting input terminal of the differential switch TWH9205 amplifier (9 feet), when the terminal voltage is lower than the inverting input terminal of the clamping voltage, that is, when irradiated with light photocell 3DU5, TWH9205 AC output high zero crossing before driving thyristor VS and conduction, XS was electric socket, electrical equipment and XS link into operation. VS according to the size of the electrical load power, the choice of triac 1 ~ 500A.
