Claims

[Scope of utility model registration request]

A control device consisting of a movable contact that interlocks with the output shaft and a fixed electrode that is provided opposite to the movable contact and on which the movable contact slides, and that is connected in series between a motor that drives the output shaft and a power source. In a motor actuator equipped with a switch, the fixed electrode is divided near at least one end thereof, and a resistor is connected in series between the fixed electrode on the one end side of the divided fixed electrode and the power supply. A motor actuator characterized by being connected.
