Description

[Brief explanation of the drawing]

Fig. 1 is a partial front view of the switch according to the above embodiment; Fig. 2 is a side view; Fig. 3 is a schematic configuration diagram showing the arrangement of contacts; Fig. 4; 5 and 6 are main part explanatory diagrams showing the operating status of the above embodiment. In the figures, 5 is an excitation solenoid core, 6 is an excitation coil, 7 and 8 are permanent magnets, 9 is a movable core, 131 is a contact support plate, 15 is an arc-resistant metal, 16, 161' is a movable electrode, and 18.20 is an electrode.

Claims (1)

[Scope of utility model registration request] A coil is wound around the center of an approximately M-shaped excitation solenoid core, and a movable core is rotatably pivoted close to the bottom of the coil, and an electrode plate is connected to the movable core with an appropriate member. Permanent magnets are fixed to the lower ends of both sides of the excitation solenoid core so that the different magnetic poles face each other, and when current flows through the coil described above, the movable core rotates in a certain direction, and the movable core rotates in a fixed direction. An automatic switch switch characterized in that the electrode plate is brought into contact with the force of two electrodes.
