遅延機能を有する電源開閉装置。 A first switch and a second switch that switch between supplying and cutting off power by opening and closing the contacts, and a switching means that controls opening and closing of the second switch;
a timer that starts operating when the auxiliary contact that opens and closes together with the contact in the first switch is switched to open or close; and a timer that controls the switching means to close the second switch after the set time of the timer has elapsed; When the first switch is switched to the power cutoff side and the first switch is switched to the power cutoff side, the auxiliary contact is switched to close or open, thereby causing the switching means to switch to the second switch.
1. A power supply switching device having a delay function, comprising: a logic circuit that provides a switching signal for controlling the opening and closing of a switch.
