Claims

[Scope of utility model registration request]

Between the pair of switching magnetic poles of an electromagnet, a coil is wound around the center of a fixed iron core having a substantially C shape, and the mutually corresponding tips are used as a pair of switching magnetic poles whose polarity is switched depending on the current direction of the coil, A rotor to which permanent magnets with poles formed in the diameter direction are fixed is arranged, a stopper is provided for regulating the swing angle of the rotor to a certain range of 180° or less, and a rotary switch is driven by meshing gears on the rotor. An oscillating rotary solenoid is provided in parallel with the rotor, and the rotary switch is interposed in a current flow direction switching circuit for the coil.
