Claims

[Scope of utility model registration request]

An electric motor equipped with a gear reduction mechanism that is activated when an operation switch is turned on and automatically stops at a predetermined position, and a cam that is engaged with the output shaft of this electric motor via a play mechanism in the rotation direction and is rotationally driven by the rotation of the output shaft. and a fixed contact disposed opposite to the movable contact, and a rotary fulcrum at a position away from the extension of the contact surface of the fixed contact with the movable contact, and the movable contact is provided at the free end of the cam. An electric switch comprising: a movable piece that reciprocates by rotational drive; and a return spring that biases the movable piece in a direction that moves the movable contact away from the fixed contact. ′
