Abstract

145,303. Cubitt, A. S. Aug. 26, 1919. Couplings combined with electric switches.-In a quick-break switch operated by a plug coupling, the contact member of the switch constitutes one arm of a toggle linkage and the contact member of the plug, when inserted, first engages mechanically and electrically with the jointed end of the contact arm and afterwards pushes the joint of the toggle inwards over the dead centre so that the switch is closed. Withdrawal of the plug upsets the toggle, and the switch member moves rapidly to the " off " position. The plug members 6 are of knife-blade form, and an additional plug 21 may be used for an earthing connexion. A double-pole switch is shown, in which the independent switch members are separated from one another by an insulating partition and are each actuated by one of the plug members. The contact arm consists of two spring plates located one at each side of the bracket plate secured to the base and held together by a pin 12, which is free to move within a gap 13 in the bracket. The spaced plates at the other end of the contact member form spring jaws, into which the plug blades may be inserted, and this end is jointed to a double link 9 having a fixed pivot at 14 in a bracket. The toggle is controlled by a spring 17 curled round a pin 18, which has a reduced central portion enabling it to be inserted into the narrow part of a key-hole slot in the bracket, where it is held by the spring, which is finally curled round the pin 12. The ends of the plug blades are cut away and laterally recessed at 15, as shown. In closing the switch, the inner shoulder of the blade acts upon the pivot pin 10 of the toggle to close the switch, and in the closed position the pin moves into the slot so that, in withdrawing the plug, it carries the pivot with it to break the switch before the circuit is broken at the plug blades. Quick action is allowed by the lost motion of the pivot pin in the slot. The lateral slot may be formed in the contact members and the pin located on the plug blades.
