ABSTRACT:
In a portable electric tool, a switch arrangement comprises a trigger on/off switch having a depressable trigger and a reversing switch having an actuating lever. An interlocking arrangement, operative between the lever and the trigger, prevents actuation of the reversing switch when the trigger is depressed. The lever comprises a pivoted bell crank, one of the legs of which carries part of the interlocking arrangement, and the other leg of which extends transversely to the trigger and engages with a slide manually slidable in an orifice in a side wall of the tool's housing to effect pivoting of the lever.
