Abstract

A bidirectional switch opens or closes a passage for fluid or the like with a simple structure whenever power is intermittently applied to an electromagnet. The switch includes a housing, and a permanent magnet, an electromagnet and a shaft installed in the housing. The housing is magnetized by the permanent magnet installed therein. Pole conversion plates made of conductive material are provided at both ends of the electromagnet. The permanent magnet has R surfaces formed at a pair of upper edges thereof, which are perpendicular to a direction along which the pole conversion plates move. The shaft is fixed to the electromagnet such that an attractive or repulsive force is generated among the pole conversion plates of the electromagnet, the permanent magnet and the housing when power is supplied to the electromagnet. Thus, the electromagnet and the shaft fixed to the electromagnet are moved.
