Abstract (en)
A motor drive switch (20) is disclosed which prevents a motor stator winding (11) from being damaged even when contact sticking occurs. In the motor drive switch (20), configuration is made with respect to a start operation of the motor such that the switching of a first contact (21) to a power source P-side terminal (3) is effected earlier than the switching of a second contact (22) to an armature P-side terminal (6), and respect to a stop operation of the motor configuration is made such that the switching of the second contact (22) to an armature N-side terminal (4) is effected earlier than the switching of the first contact (22) to an armature P-side terminal (1).
