イツチ。 a switch case to which at least one pair of terminal pieces are fixed; and a switch case that is fitted into a guide hole formed in the upper wall of the switch case and elastically supported so as to be movable up and down by a return spring within the switch case. A push button, a movable contact piece having a distal end fixed to it that makes contact with and separating from a fixed contact on one side of the one terminal, a movable contact piece having a proximal end electrically connected and fixed to the other terminal piece, and a movable contact piece having a proximal end electrically connected and fixed to the other terminal piece. A movable spring piece that is supported by a fixed body on one side of the one terminal and is driven by a pushing operation of the push button, and a movable spring piece that is stretched between the tip of the movable contact piece and the tip of the movable spring piece. and a substantially inverted U-shaped actuating spring that snaps the movable contact piece in reverse at a predetermined pushing position of the push button,
A push button switch characterized in that a locking position between the operating spring and the tip of the movable contact piece is set closer to the tip than a position where the movable contact is fixed in the movable contact piece.
