ABSTRACT:
An actuation device for a switch of a hand machine tool, particularly for a Totmann switch which provides for fatigue-free operation. The actuation device includes a front wall provided with a locking projection engageable in a recess formed in the wall of the switch housing. A restoring spring acts on an actuation member. Two spaced ribs with inclined surfaces are provided on the housing wall. The locking projection slides along the inclined surfaces of the spaced ribs. The locking projection may be broken away from the front wall of the actuation member whereby the end of the front wall would slide along the inclined surfaces of the ribs.
