Claims (1)

[Scope of utility model registration request] an operating member provided on the case so as to be operable in two stages between an original position and first and second operating positions on the forward rotation side and reverse rotation side; and an operating member provided on one of the case and the operating member. A pressure contact formed on the other of the case and the operating member cooperates with the pressure contact to operate the operating member to the first operating position, and then the operating force is released. an inclined part for returning the member to its original position; a holding part for holding the operating member in the second operating position when the operating member is operated from the first operating position to the second operating position; and the operating member. a forward rotation switch and a reverse rotation switch for forming a forward rotation circuit and a reverse rotation circuit of the motor when the member is operated to first and second operating positions of the forward rotation side and reverse rotation side, respectively; and the case. one return member made of a shape memory alloy, which is provided in the motor and is provided with a current flowing to the motor through the forward rotation circuit and the reverse rotation circuit when the operation member is operated to at least a second operating position. , the return member is self-heated by the lock current when the motor is locked and returns to the memorized shape, thereby returning the operating member from the second operating position to the first operating position and back to the original position. 1. A motor control switch device, characterized in that the motor control switch device is configured to
