Polarized electromagnetic relay |
摘要 |
A polarized electromagnetic relay includes a flat-shaped armature pivotally supported at its center, an electromagnet with a pair of pole members extending toward the armature ends on either side of the center pivot axis, and a three-pole magnetized permanent magnet bridging between the pole members in generally parallel relation with the armature. A pair of movable contact springs extends along the lateral sides of the armature and joined at its center portion to the armature to be movable therewith. Integrally formed with each movable contact spring is a pivot arm which extends transversely from the center thereof and is fixedly secured to a relay casing. The pivot arm defines itself a resilient torsion element of limited deformability by which the armature is supported on the relay casing and is permitted to pivot about the center pivot axis for movement between the two angular positions.
