  • a pawl for actuating an electrical on / off switch for the electric motor is arranged.
  • the pawl is formed as a pivotable about a pivot axis on the handle fixed rocker with two rocker arms, at the lower rocker arm a switch pin of the on / off switch rests under the force of a switching spring.
  • the pawl can be latched in chisel operation via a locking device in a detent position. However, a detent position during drilling operation is avoided.
  • the latching device has a first locking element arranged on the pawl and a second latching element which is arranged on a pivoting lever mounted on the housing in an articulated manner.
  • the pivot lever is coupled to a toggle switch for manually switching from drilling to chisel operation and vice versa arranged eccentric cam, on the circumference of the pivot lever is pressed by a compression spring.
  • a Bohr adjusting switching position of the switch knob which is arranged on the pivot lever detent element is outside a switching path of the arranged on the pawl latching element.
  • adjusting switching position of the switch knob of the pivot lever is moved via the eccentric cam with its locking element in the switching path of the arranged on the pawl latching element.
