Abstract
An arc quenching device, which prevents a load device from displaying an unnecessary behavior during starting of a power supply, includes: a semiconductor switch connected in parallel to a first switch which is mechanical; a power supply circuit configured to use a voltage which is generated between both contact points of the first switch to output a voltage which causes the semiconductor switch to turn on; and a second switch configured to cause its open state to prevent the semiconductor switch from turning on.
