Abstract

650,207. Electromagnetic relays. JOSEPH, R. J., and SHIPTON & CO., Ltd., E. Nov. 29, 1948, No. 30981. [Class 38(v)] In high speed polarized relay bouncing of the contacts is reduced to a minimum by supporting the moving contacts 14 on the balanced armature 8, 8<SP>1</SP>, by a spring arrangement comprising a central leaf spring 19 which carries at its free end an insulating disc 22 through the centre of which passes a metal stud the ends of which form the contacts, side springs 23 being also arranged so as to press with their free ends against the disc 22. Preferably the spring 19 has a hole and the disc 22 is moulded into position, some of its material passing through the hole. The co-operating "fixed" contacts are also mounted on leaf springs and are adjustable by a nut 34 or a screw, Figs. 6, 7 (not shown). The armature may carry additional contacts 14 mounted on additional leaf springs and co-operating with additional fixed contacts. The armature consists of two plates 8, 8<SP>1</SP>, which grip between them the centre portion of a blade spring 9 fixed at its ends, thereby forming a pivotal mounting for the armature. The upper and lower ends of the armature are situated opposite the poles of a permanent magnet and its lower end moves in the gap between the poles of the electromagnet 6.
