Claims

[Scope of utility model registration request]

(1) The forward and backward movement position of the slider held in the switch body is determined by a heart cam groove on the slider side, one end of which engages with the groove, and the other end of which is held on the switch body side with a base pin. In addition, in the push button switch in which the movable contact on the slider side is opened and closed with respect to the fixed contact on the switch body side, a plate is provided with a locking piece portion and a retaining piece portion by bending into two. form a spring,
The plate spring is held in the switch body at a position where the locking piece faces the note cam groove, and a step provided at the middle part of the lock pin is a locking piece provided on the locking piece of the plate spring. By locking the lock pin in the receiving part and slidably inserting the other end of the lock pin into the retaining hole provided in the retaining piece of the leaf spring, one end of the lock pin is controlled by the spring force of the leaf spring. A push button switch, characterized in that the lock pin is held in elastic contact with a heart cam groove, and the lock pin is held on the switch body side so as to be slidable only in a plane perpendicular to the direction of movement of the slider. (2) The switch body is composed of a wafer and a case attached to the wafer, and the heart cam groove of the slider is located between the wafer and the case in a plane perpendicular to the direction of movement of the slider. A retention hole having a long axis parallel to the formed surface is formed. By holding the lock pin in the engagement hole, the lock pin is held on the switch body side so that it can slide only in a plane perpendicular to the direction of movement of the slider. A push button switch as described in Range 1.
