Abstract

1436275 Mechanical switches CUTLERHAMMER WORLD TRADE Inc 12 Feb 1974 [12 Feb 1973] 06401/74 Heading H1N In a power tool having a trigger 24, Fig. 2, for energizing the electric motor and a lock pin 28 for optionally latching the trigger, a reversing switch 14 is mounted adjacent the lock pin 28 and is operable by a hollow cylindrical knob 100 mounted concentrically of the lock pin bushing 123. The knob 100, Fig. 3, is coupled to a slider 95 of the reversing switch by a flexible hinge 99 and carries an interlock projection 114 engageable in grooves 114, 116 of the trigger 24 whereby it prevents operation of the trigger 24 by engagement with a central projection 120 if not fully moved to one of its two positions. The arrangement also prevents the knob 100 from being switched over while the trigger 24 is operated. The reversing switch comprises a housing 60 fixed by studs 62, 63 to the body 44 of the main switch and enclosing the rectilinearly moving slider 95 carrying a pair of bridging contacts 110, 112 in recesses (107), (108), Fig. 6 (not shown). The contacts 110, 112 slide over fixed contacts 70-73 located in recesses 68 of the housing 60 and retained in position by a hinged cover 76 with a friction fitting closure. The two operating positions of the slider 95 are located by a detent 101 engageable in a pair of recesses 102, 103.
