Abstract

1,019,390. Electromagnetic relays. STANDARD TELEPHONES & CABLES Ltd. Feb. 22, 1963 [Feb. 23, 1962], No. 7266/63. Heading H2B. At least one contact blade 7 of a sealed magnetic contact unit 1 is longitudinally slotted at its free end to divide its contact surface into two portions 9, 10 of unequal width. Such an arrangement minimizes contact bounce since one portion 9 will be magnetically moved into engagement with its co-operating contact 6 before the other portion 10. Such a magnetic contact blade may be used in a make-beforebreak change-over contact unit. The slot may be at an angle to the longitudinal axis of the blade. In an alternative arrangement the slot is triangular or ends in a circular aperture. In another arrangement the blade is divided into three unequal portions by two slots. The rigidity of the portions may be varied relative to one another by embossing.
