ABSTRACT:
A switch includes a fixed contact having a first conductor portion connected to a terminal, a second conductor portion having a stationary contact, and a third conductor portion. The third conductor portion is disposed on the side of the other end of a moving contact to which a traveling contact is not mounted with respect to a position of the stationary contact, and on the side opposed to the terminal. The first conductor portion is disposed above a contact surface of contacts at a contact closing time, and is disposed below a contact surface of the traveling contact at a contact opening time. A position of the first conductor portion which can be surveyed from a surface of the traveling contact at an opening time of the contacts is coated with an insulator. Thereby, it is possible to provide an excellent current-limiting performance since an entire current path of the fixed contact generates electromagnetic force to stretch an arc on the side of the terminal, and since the arc is cooled by vapor generated from the insulator.
