Abstract

928,512. Retractive switches. N.S.F. Ltd. May 3, 1961 [Feb. 3, 1960], No. 3866/60. Class 38 (5). In a retractive switch suitable for use in an electric power tool, the insulating operating trigger, preferably made of nylon, has a pivotpin 17 moulded integrally therewith to extend between the sides 16 of the trigger. The trigger is pivoted in slots 23 formed in the end of a support member 12 which is secured to a contact housing 10 by a strap 13. Pivotally connected to the trigger at 18 is an axially movable switch actuating member 14 having a down-turned end 15 co-operating with contact moving parts of the switch, not shown. The actuating member 14 is biased to the left by a spring 20 which is secured to the support 12 and to one limb of an L-shaped link 21 which is pivoted at 18, the other limb of the link engaging the upper surface of the actuating member. Specification 928,511 is referred to.
