Abstract

PROBLEM TO BE SOLVED: To provide a switch device capable of coping with short stroke while keeping the prescribed gap dimension between contact points, related to the structure of a fast moving switch device. SOLUTION: A conductor plate 8 to which a movable contact point 9 is tightly fitted is displaced in the direction almost vertical to the slide shift direction by the spring property of a spring member 10, to contact/depart from a fixed contact point 2a by a slide member 11 at which first and second operation surface parts 11d and 11e are formed. First and second abutting parts 8c and 8d which abut the first and second operation surface parts 11d and 11e are formed at the conductor plate 8. As the slide member 11 slides, the first operation surface part 11d slides against the first abutting member 8c so that the conductor plate 8 is displaced in the direction almost vertical to the sliding direction, while the second operation surface part 11e slides against the second abutting part 8d, to press the movable contact point 9 of the conductor plate 8 toward the fixed contact point 2a.
