The lower section of the spring element being divided into an upper contact portion and a lower contact portion having a length larger than the upper contact portion. The contact spring element is then housed in a casing provided with fixed contacts. The contact spring element being pivotally supported though a support shaft in the casing while contacting the lower contact portion with a first fixed contact and striking an upper plate of the holder against a stopper to stop upward pivotal movement of the holder due to the restoring force of the spring element.
