15n) is sent to the gate of the light receiving ~ (6n), and the unidirectional semiconductor switch Ill f: If you want to operate a time switch other than manual operation, connect a mechanical relay for a minute load to the time switch terminal. , and the excitation coil of this mechanical relay had to be excited by the output of the time switch, which had the drawback of a complicated configuration and a large device. Further, since the output of the time switch is maintained at H level, there is a drawback that manual switches (20 m) to (20 m) connected in parallel to the time switch cannot be operated.
