Abstract

PURPOSE:To reduce a stroke to make a contactless micro switch small-size and long-life by moving two permanent magnets, which diminish mutually the magnetic flux density, in one body and arranging a magneto-electric onverter between these two permanent magnets. CONSTITUTION:Two permanent magnets 40 and 50 are fixed to a moving piece so that magnetic poles of the same polarity may be opposite to each other at a prescribed interval, and Hall IC 30 is arranged between these two permanent magnets. Magnetic flux density B which turns on Hall IC 30 is generated by permanent magnet 40, and the magnetic flux density which diminishes magnetic flux density B is generated by permanent magnet 50. Then, the mvong piece is driven on a basis of the external operation to reciprocate permanent magnets 40 and 50 along the line, which connects them, in one body, and one permanent magnet goes away from Hall IC 30 when the other permanent magnet approaches Hall IC 30.
