Abstract

PURPOSE:To hold driving shafts under non-energized condition at right and left opposite-end positions by arranging annular magnets at both sides of a driving coil. CONSTITUTION:Annular permanent magnets 4, 4' are fixed to the arms 1a, 1a' of ?-shaped yokes 1, 1'. Collars 6, 6' and driving shafts 2, 2' are installed at the opposite ends of a plunger 5. When a driving coil 7 is under non-energized conditions, the plunger 5 is magnetized by the magnets 4, 4' and stabilized at either of right or left position. With a current flowed to a coil 7 when the plunger 5 is located at left, the plunger 5 moves towards right when the magnetized direction of the plunger 5 by this current is opposite to the magnetized direction by the magnet 4, and the driving shafts 2, 2' are held at right by the magnet 4'.
