Claims

[Scope of utility model registration request]

A slider is springed onto a plate-shaped movable contact via a spring at the bottom of an inverter provided on the operating handle, and a pair of circles are formed at the center of the length on both sides of the movable contact in the width direction. The arc-shaped recesses are placed on both sides of the support fitting in elastic contact with a pair of arc-shaped protrusions formed in the center of the length direction, and the movable contact is moved by seesawing by operating the operating handle. In a seesaw swing type switch that turns on and off the contacts of a contact, slip-prevention pieces for preventing the movable contact from slipping are erected on both sides of the length direction of each of the arcuate protrusions, and one of the arcuate protrusions The slide prevention piece on the side is made shorter than the slide prevention piece on the other arcuate protrusion side, and the detachment prevention piece that prevents the movable contact from coming off upward is placed opposite to the tall slip prevention piece. A structure for preventing detachment of a movable contact in a switch provided with the switch.
