Abstract

A hand-held power tool includes a tool housing and a handle housing. The handle housing is movable relative to the tool housing. The hand-held power tool also includes an electric motor for driving the hand-held power tool. The electric motor is switched on and off by a relative movement of the handle housing relative to the tool housing. The hand-held power tool also includes a main electrical switch configured to apply an electrical voltage supply to the electric motor. The main electrical switch is switched by an actuating mechanism. The main electrical switch is actuatable with the aid of a movable component that is movable relative to the tool housing handily via the actuating mechanism, either directly or by the actuating mechanism.
