Abstract

PURPOSE:To locate a single plunger at three positions by a method wherein magnets are arranged so that different poles oppose mutually, a yoke is mounted into the magnetic fields and the currents of coils wound on yoke arms are controlled. CONSTITUTION:A ring 15 which can turn centering around a supporting shaft 13 is provided with magnets 16, 17 polarity thereof mutually differs. A yoke 3 is mounted into the magnetic fields, the yoke 3 has arms 4, 5, 6 radially extendig and coils 8, 9 are wound on the arms 5, 6. A rotary plunger is formed in this manner. When currents are not flowed through both coils 8, 9, th ring 15 is located at a neutral positon; when currents are flowed through either one of the coils 8, 9, the ring 15 rotates left or right holding the neutral position. Thus, the single plunger can be located at least three positions.
