WIPO Patent Application WO/2018/131248
Kind Code:
A1
Abstract:
Provided is a highly reliable, compact and inexpensive device. An arc-quenching device (2) is equipped with a semiconductor switch (TR4) connected in parallel to a mechanical first switch (SW1), a constant voltage circuit (22) for outputting a voltage which switches the semiconductor switch (TR4) on by using the voltage produced between the two contacts of the first switch (SW1), and a second timer circuit (23) for switching the semiconductor switch (TR4) off after a prescribed amount of time has elapsed since switching the semiconductor switch (TR4) on.
