ABSTRACT:
A relay includes a base block (A'), an armature block (B') having a pair of armatures (8a, 8b) and a permanent magnet (17a, 17b), and an electromagnet block (C') having an approximately U-shaped core (10). Magnetic pole legs (18a, 18b) of the electromagnet block are inserted through the armatures into the base block, to thereby sandwich the armature block between the base block and the electromagnet block.
