Abstract

PURPOSE:To form thin shape without damaging sensitivity by engaging a - shaped slat yoke, to a central horizontal piece thereof an excitation coil is mounted, and a ?-shaped armature formed by connecting one ends of two soft magnetic substance plates by a permanent magnet. CONSTITUTION:The excitation coil 3 is wound on approximately center of the central horizontal piece 2b of the -shaped slat yoke 1 through a coil bobbin, and an electromagnet block 9 is formed. The left ends of the soft magnetic substance plates 4a, 4b disposed up and down in parallel are connected by the permanent magnet 5, and a ?-shaped armature block 6 is formed. The pole contacting surfaces 8a-8d of each soft magnetic substance plate 4a, 4b of the armature block 6 are each opposed to the pole contacting surfaces 7a-7d of the electromagnet block 9 at proper intervals, and combined. Accordingly, since the magnetomotive flux of the excitation coil flows through the yoke and the soft magnetic substance plates and does not flow in the permanent magnet, reluctance is small, sensitivity is high, and thin shape can be formed.
