Claims

[Scope of Claim for Utility Model Registration] An electric motor, an output shaft that rotates in response to the driving force of the electric motor, a contact mount that is linked to the output shaft, and a movable contact attached to the contact mount that connects and separates. A motor actuator having a printed circuit board having a fixed contact, wherein the movable contact is made wider near an end of the fixed contact on a side away from the fixed contact to increase the area in contact with the movable contact. A motor actuator characterized by:
