Claims

[Scope of utility model registration request]

A case in which a normally closed contact and a normally open contact are arranged vertically side by side, a push button shaft whose upper end protrudes from the upper surface of the case and is inserted vertically slidingly toward the case, and a push button shaft at the upper end of the push button shaft. A return spring, which is a coil spring that is fitted onto the upper end of the push button shaft with its upper and lower ends in pressure contact with the formed flange and the top surface of the case, and which applies an upward spring return force to the push button shaft; It has a plurality of stopper protrusions that integrally protrude in the vertical direction of the outer peripheral surface and a through hole that passes through the push button shaft in the center,
An insertion groove is cut into the inner circumferential surface of the through hole to allow the stopper projection to be inserted therein, and a recess with an open top surface that is closed on the lower surface and engages with the lower part of the stopper projection when inserted from below is formed. A ring is formed on the inner circumferential surface of the through hole to be offset from the insertion groove, and a plate-shaped body is attached to the push button shaft by locking the lower surface to the upper surface of the stopper protrusion. A contact is formed with a movable contact that selectively contacts the open contact, and a push button shaft passes through the contact at its lower end, the upper end is engaged with a ring, and the contact is fitted onto the push button shaft. A coil spring consisting of a contact pressing spring that presses the movable contact on the bottom surface of the contact to the normally open contact when the movable contact on the top surface of the contact is separated from the normally closed contact when the push button shaft moves downward. push button switch.
