When the power is applied to the solenoid 19 in the initial position state, that is, in the normal state in which power is not applied to the power supply coil 3, the solenoid 19 generates magnetic force to guide the plate 11. The rotating member 16, which was located at the 'I' position of), is pulled out. Accordingly, the rotation member 16 is rotated by the slot 11b formed on the arc surface of the guide plate 11 to be positioned at the 'ga' position of the guide plate 11. At this time, the rotating member 16 is moved from the 'I' position to the 'ga' position as shown in Figure 8a and 8b the moving member 31 is inserted into the guide groove (19a) of the solenoid 19 Pushed. Accordingly, the movable member 31 moves within the gap between the expansion grooves 19b, and pushes the contact plate 32 so that its contact 32a contacts the terminal 34 to form a star connection.
