Abstract

A handheld power tool, in particular a power drill or power screwdriver, has a tool holder, which is displaceably received in a housing and which can be driven via a drive unit; a microswitch that can switch the drive unit on and off is provided, which is switchable upon an axial displacement motion of the tool holder via an actuating element. The actuating element is joined axially solidly to the tool holder, so that the axial displacement motion of the tool holder at the same time acts as the displacement motion of the actuating element, which motion actuates the microswitch.
