Claims

[Claims for Utility Model Registration] (1) A switch case, an actuator that can be moved relative to the switch case between a normal position and a pushbutton operation position, and a fixed contact disposed on the switch case. a movable blade disposed on the actuator and having a movable contact that can come into contact with the fixed contact or move away from the fixed contact as the actuator moves; and between the switch case and the actuator a return spring provided between the actuator and the movable blade for applying a force to shift the actuator to the normal position; and a return spring provided between the actuator and the movable blade to apply a force to the movable blade toward the fixed contact. In a pushbutton switch of the type equipped with a movable blade restraining spring that provides a restraining force, the actuator is provided with a cavity for accommodating the movable blade, and the cavity is arranged in the direction of movement of the actuator. guiding means are provided for guiding the movable blade to move relative to the actuator against the restraining force of the movable blade restraining spring in the same direction, and In the vicinity of the empty space, the movable contact of the movable blade is brought into contact with the fixed contact in the push button operation position, and the movable contact of one of the movable blades is further disposed immediately before the actuator is pushed down to the final depression position. Engagement means is provided for engaging the edge and applying a rotational force to the movable blade such that the contact surfaces of the movable contact and the fixed contact rub against each other. Push button switch. (2) The scope of the utility model registration claim, wherein the wall portion of the vacant space on which the movable blade is pressed by the movable blade restraining spring is inclined with respect to the contact surface between the movable contact and the fixed contact. No.
Push button switch described in (1). (3) The engaging means is a protruding shoulder formed on the peripheral wall of the void, as claimed in Claim No. 1 of the Utility Model Registration.
) or (2).
