Abstract
A rotary hammer comprises an electric motor having its longitudinal axis perpendicular to the axis of the hammer spindle and the tool holder. A single switching element activates and deactivates the hammer mechanism and the rotary drive for the tool holder. The switching element has an eccentric actuating section extending parallel to the main axis of the switching element, acting on a coupling part to activate and deactivate the hammer drive. The switching element has a cam section acting on a slider part to engage and disengage a coupling sleeve (non-rotatable on the hammer spindle) with a drive sleeve to thereby engage and disengage the rotary drive of the hammer spindle.
