PURPOSE: To provide a switch device, without adverse effect to the life span of a load even when the speed of pushing operation is high, an which can respond to the variety of long and short strokes in the same structure of contact points by considering not to generate a bounce large enough to separates the respective contact points, and by stopping the self-advancement of a fast moving mechanism by abutting other members than a slide member.

CONSTITUTION: A plate spring 6 is penetrated by the first locking protrusion 3a of a common terminal 3 to provide a locking notch, with which the one end surface 6d of the plate can be abutted on the locking protrusion 3a. The end surface 6d of the locking notch is abutted on the first locking protrusion 3a directly after a mobile contact point 4a is brought into contact with a fixed contact point 2a, and the position of the plate spring 6 is thus controlled.
