    Patent number: 5432387
    Abstract: A switching means is provided in a power source line for supplying the A.C. power source of a main power source circuit. A lock switch is separately provided. In the normal state, the lock switch is in a locked off state, thereby controlling the on-off operation of the switching means by the automatic on-off function based on a power source operating switch and timer etc. By turning the lock switch off, the switching means is locked, thereby overriding the automatic on-off function and the power source operating switch.
