Relay structure

Abstract

A relay structure advantageous for compacting purpose is disclosed herein. The relay comprises a generally L-shaped yoke having an upright yoke leg and an upper yoke member extending substantially at a right angle thereto, the upright yoke leg being connected to one end of the core of an energizing coil which extends substantially in parallelism with said upper yoke member. The upper yoke member is formed with a center slot extending longitudinally thereof to be open at both longitudinal ends. A generally L-shaped armature is hingedly supported onto the free end of the upper yoke member with a tab extending across the air gap defined between the free end of the upper yoke member and the opposite end of the core. Extended from the upper end of the tab is an actuator arm which is received in said slot and on which overlies a spring blade carrying at its free end a movable contact. Upon hinging movement of the armature in one direction in response to the coil being energized, the actuator arm presses upwardly the spring blade to engage or disengage the movable contact from a cooperating fixed contact. Conversely, when the coil is deenergized the armature is driven to hinge in the opposite direction by the biasing force from the spring blade to disengage or engage the movable contact with the fixed contact.
