Abstract

1416041 Retractive switches SKIL (NEDERLAND) NV 5 Jan 1973 [14 Jan 1972] 811/73 Heading H1N A trigger operated switching device for portable tools has an automatically engaging manually released safety catch to prevent the switch being closed inadvertently. In Fig. 1 a trigger 4 of insulating material slides within a metal or insulating frame 6 holding an opentopped insulating base 2 housing the switch components and the trigger is spring biased into an OFF position (switch contacts open) where it is held by engagement of a detent 10a of a rigid locking lever 10 located within a slot 16 of the trigger and having one end accommodated in a notch 18 for limited pivotal movement within the slot. As shown in Fig. 3 the lever 10 is angularly arranged in the slot and has its detented end outwardly biased by a spring 12 so that when the trigger is released after being depressed it is biased by a spring 8 to the OFF position and the detent 10a automatically engages in a hole 6b (Fig. 2, not shown) in the frame 6 and firmly locks the trigger in this position unless it is released by depressing a button 20 which is retractively movable in a sleeve 6c and which carries a shaft 20a which engages the locking lever 10 to release the detented end.
