Abstract: A relay comprising a small, flat, rectangular, dielectric housing. A coil mounted in the center of the housing. A U-shaped steel armature at the rear end of the coil having a central arm extending into the coil approximately half way through. A U-shaped steel armature mounted in a teflon slide at the front end of the coil and having a central arm extending into the coil approximately, 0.020 inch from the rear arm. The teflon slide being slidable along the rear armature side arms against the action of a leaf spring. A pair of contact prongs extending from the front of the housing and having integral portions in the housing bent at right angles toward each side and then bent again toward the rear. A movable contact arm extending rearwardly from each inner prong arm toward a rear contact at each rear corner of the housing. The movable contact arms being normally spaced from the rear contacts approximately 0.018 inch. Each contact arm has an enlarged annular portion at the center.
