PURPOSE: A bidirectional switch is provided to stably perform an open and close function by reducing the frequency of accidents. CONSTITUTION: Two permanent magnets(21,22) are installed inside a housing(10). An electromagnet(30) generates a magnetic force according to power supply. A pole conversion plate is equipped on both ends of the electromagnet. A shaft(40) is fixed to the electromagnet. The two permanent magnets are installed on the vertical units on both sides of the housing.
