JPS6460935A - Magnetic sensor of relay - Google Patents

Abstract

PURPOSE:To provide easy mounting to a narrow electronic circuit base board without bringing about voltage drop to a relay circuit by combining in electrical insulation with practicability of actuating a reed switch when micromagnetism is sensed which leaks at the time of relay actuation. CONSTITUTION:A reed switch 1 is placed on the diagonal of a square base board 4 made of synthetic resin, and 3 protrude in the opposite directions to each other. Covered conducting wire 5 is connected at the outer edge mating. A fixed layer 6 in which these members are covered with, for ex., synthetic resin adhesives, is fixed to the base board 4. Together with the reed switch 1 a relay 7 placed on this fixed layer 6 is covered with, for ex., a thermoshrinking tube 8 of synthetic resin and fixed to the reed switch. When this magnetic sensor is fixed, for ex., to a concentrated terminal plate of a rotary drum type game machine, a relay contact signal b is given to an incorrect action inspecting terminal of the concentrated terminal plate. The reed switch actuates the electrical load, for ex., a chime.
