The present invention includes a first switch 4a, a second switch 4b and a capacitor 4d. The first switch 4a normally in a closed state is connected in series between a power source 1 and load, and opens when an accident builds up. The second switch 4b normally in an open state closes almost simultaneously with the opening of the first switch 4a. The capacity 4d normally charged by an arbitrary voltage has predetermined electrically capacity. The serial connected circuit consists of the second switch 4b and capacitor 4d, it is connected in parallel to the first switch 4a.
