Abstract: PURPOSE:To reduce the manufacture cost and to attain miniaturization by using the 2nd photocoupler to control that the optical coupling by the 1st photocoupler is attained near a zero point of an AC voltage waveform of a main circuit when a control input voltage is applied. CONSTITUTION:When a prescribed control input voltage is applied between control input terminals 1 and 2, although output terminals 3, 4 are kept open until an AC voltage waveform reaches in the vicinity of zero point and tye are closed after the waveform reaches the vicinity of zero point. When the AC voltage waveform reaches the vicinity of zero point and an AC voltage is lowered than the forward voltage VF, since no drive current flows to light emitting diodes 23, 24 they are not lighted and a transistor 25 is turned off. Thus, a drive current flows to a light emitting diode 20 of the primary side of a triac coupler 22, which is lighted, a triac 5 of a main circuit is triggered and turned on, the output terminals 3, 4 are closed and the switch control by zero cross system is attained.
