Abstract
1399198 Retractive switches STANDARD TELEPHONES & CABLES Ltd 17 May 1973 23530/73 Heading H1N A retractive snap-action changeover switch having make-before-break features is actuated by deflection of an electrically conductive helical tension spring 12, by means of a lever 15, until the spring force acts below the pivot point 7 of an arm 9 carrying a movable contact 10 whereupon the movable contact 10 disengages from contact with a fixed contact 4 and engages a fixed contact 5 with a snap action but in so doing the spring 12 which is electrically connected to contact 10 by being attached to arm 9 first engages an auxiliary resilient contact 13 which is electrically connected to the fixed contact 5 by being welded to a common terminal member 3. The auxiliary contact 13 is of phosphor bronze or beryllium copper and for some applications of the switch the fixed contact 5 may be dispensed with.
