Polarised electromechanical relay - has pivot mounted armature block mounted on main coil block with leaf spring contact carriers attached

摘要

A polarised electromechanical relay has a main housing (10) within which there is an actuator coil assembly. The coil is located within the core of the actuator that has pole pieces (31) on the upper surface. When energised the coil generates a field to displace an armature (50). This is in the form of a metal bar (51) that is mounted to rock about the centre point. Coupled to an insulated carrier (57) are leaf spring contact arm (53). The contacts (55) engage those formed (45) on the main housing. ADVANTAGE - Reliable operation with high voltages.
