Abstract
A device for switching operating modes for an at least partially rotational and percussive hand tool machine having an overload clutch, which is arranged between a hollow driving guide cylinder (3) containing an axially striking impact piston (2) and a rotating, driving crown gear (4) on the guide cylinder (3) and which can be switched into different operating modes using an externally manually switchable, axially displaceable switching member, wherein at least one operating mode is rotationally driven, wherein the axially displaceable switching member engages rotationally form-lockingly into a freely rotational coupling ring (6) of the overload clutch mounted relative to the guide cylinder (3).
