Abstract
A plunger is movable between a first position and a second position. The plunger separates a first movable contact from a first fixed contact and separates a second movable contact from a second fixed contact at the first position. The plunger presses a first movable piece toward a first fixed terminal to make the first movable contact into contact with the first fixed contact, and presses a second movable piece toward a second fixed terminal to make the second movable contact into contact with the second fixed contact at the second position. The plunger moves from the first position to the second position by being pressed by a pressing portion of an electric plug inserted into a third insertion port.
