Claims

[Scope of utility model registration request]

A pair of operators that are provided on the base so that they can be pushed into the base and are normally biased to the original position; a cam portion that is provided on each of these operators and has a cam groove around the cam protrusion; and these cam portions. The proximal end portion is supported by the base, and the distal end portion is provided in a hook shape so as to be movable along the cam groove, and the cam portion is provided with a cam action by the cam portion each time the operator is pushed in. a pair of lock pins that alternately repeat an action of receiving the cam part and holding the operating element in the push-in position by engaging the tip part with the cam part, and an action of releasing the engagement and returning it to the original position; The lock pins are movably provided between the lock pins, and when the operator corresponding to the other lock pin is pressed while one lock pin is engaged with the cam protrusion, the lock pin is pushed and displaced to the cancel position by the other lock pin. and an actuating member for forcibly releasing the engaged state of the lock pin and the cam protrusion without going through a regular disengagement operation, wherein the operating element is pushed into the cam groove until it reaches the deepest pushed position. An auxiliary groove is formed to allow the tip of the lock pin to escape when operated, and when the tip of the lock pin enters the auxiliary groove, the actuating member is pressed and displaced by the lock pin to the cancel position. A switching operation device characterized in that the switching operation device is positioned so that the
