Claims

[Scope of utility model registration request]

(1) 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, a cam that engages with the output shaft of this electric motor and is rotationally driven by the rotation of the output shaft, and a fixed contact. , the movable piece has a rotation fulcrum at a position apart 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 movable piece, which rotates back and forth by the rotational drive of the cam, and a predetermined movable piece. An electric switch comprising: an engaging pawl that is driven by the rotation of the output shaft and rotates the movable piece when a larger return force is required.

(2) The electric switch according to claim 1, wherein the cam is engaged with the output shaft via a rotational play mechanism.
