Abstract

1370016 Retractive switches LUCERNE PRODUCTS Inc 28 Oct 1971 [1 April 1971] 50264/71 Heading H1N In an electric switch for a portable power tool, the contact carrier 16 of the switch is actuated by a trigger T mounted externally of the switch on a part 12 of the switch casing 10, by a pivot 33. An actuating rod 18, integral with the contact carrier 16, has a U-shaped portion 38 which locates over a pin 54 integral with the trigger. When the trigger is depressed against the action of the bias spring 40, the actuating rod 18 and thus the carrier 16 are moved longitudinally of the casing to operate the switch contacts (Fig. 4). A push button 60 may be provided to retain the trigger in the depressed position. Specification 1,261,244 is referred to, disclosing a suitable on/off switch and rheostat for use with this invention.
