Claims

[Scope of utility model registration request]

a case having a fixed contact; a blade having a movable contact that is swingably provided in the case and cooperates with the fixed contact to configure a switch; and a blade having an original position and a first and second operating position in the case. an operating member provided in between so as to be operable in two stages; and an operating member provided on this operating member that applies a pressing force to the blade to normally urge the operating member to its original position to fix the movable contact of the switch. Pressure welding to bring the movable contact of the switch into the off state where it is spaced from the contact and at the same time to swing the blade when the operating member is operated to the first and second operating positions to bring the movable contact of the switch into the on state where it is in contact with the fixed contact. a slope portion provided on the blade and cooperating with the pressure contact to return the operating member to its original position when the operating force is released after the operating member has been operated to the first operating position; The operating member passes through the first operating position and then moves to the second operating position.
a holding part that holds the operating member in its second operating position when the operating member is operated into the operating position; and a return member made of a shape memory alloy that is provided in the case and is supplied with a current flowing to the motor via the switch. the return member is self-heated by the lock current when the motor is locked and returns to the memorized shape, thereby moving the operating member from the second operating position to the first operating position. A motor control switch device, characterized in that the motor control switch device is configured to return the motor to its original position after a period of time.
