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 fixed contact has a rotation fulcrum at 21 on the outside of the extension of the contact surface with the movable contact, and at its free end is provided with a movable movable piece that is reciprocated by the rotational drive of the cam. Characteristic electric switch.

(2) The electric switch according to claim 1, wherein the gear reduction mechanism includes a one-way clutch at its final stage, and the driven side of the clutch is fixed to the output shaft. .

(3) The electric switch according to claim 2, which is a registered utility model, characterized in that a manual operation knob is fixed to one end of the output shaft so that the output shaft can be manually rotated from the outside.

(4) Utility model registration claims 1 to 3, characterized in that the movable piece is provided with a roller that engages with a cam, and the movable piece is reciprocated by the cam via this roller.
