Claims

[Scope of utility model registration request]

A push button is fitted into a guide hole formed in the upper wall of the switch case and is elastically supported by a return spring in the switch case so as to be movable up and down, and at least one pair of push buttons fixed to the switch case a movable contact piece that is electrically connected and fixed to one of the terminal pieces and has a movable contact at its tip that contacts and separates from the fixed contact of the other terminal piece; and a movable contact piece that is supported by a fixed body on one side of the one terminal piece. a movable spring piece whose tip end passes through a frame formed at the lower part of the push button switch and is driven by the pushing operation of the push button; an actuating spring that is hooked between the tip of the contact piece and reverses the movable contact piece in a snap-like manner when the push button is pushed in a predetermined amount; A curved portion for extending and displacing the movable contact piece prior to the reversing operation is formed on the base end side of the movable contact piece, and an upward protrusion that pushes up the movable spring piece from below when the push button is released from the push button is formed on the base end side of the movable contact piece. A push button switch characterized by being formed in the frame.
