Abstract

999,856. Electromagnetic relays. GENERAL ELECTRIC CO. June 19, 1962 [July 3, 1961], No. 23499/62. Heading H2B. In a relay comprising a housing, an axially movable metallic sleeve 55, an armature 57 slidable on said sleeve and arranged to move it between two positions, a cap 65 secured around said sleeve and a spring 69 mounted between the armature and cap, the sleeve is split axially to reduce eddy currents. The sleeve is preferably of brass and carries a contact bridge 59 at one end which co-operates with fixed contacts 77. The operating characteristics of the relay are set during manufacture by suitably positioning the cap on the sleeve where it is held by the resilience of the sleeve. The housing comprises three interfitting parts 5, 7, 9 which are held together by means of a pin 13 which passes through them and a spring fastener 21. The housing has a plurality of projections 107, 109 which co-operate with slots 103, 105 in a mounting frame 95 so that the relay may be mounted in many orientations. When the relay is energized armature 57 moves upwards, compressing spring 69, thereby urging sleeve 55 and contact bridge 59 upwards. On de-energization, the armature strikes the contact bridge a hammer-blow and so breaks any weld which may have been formed.
