Abstract

A battery-operated screwdriver (10) with a housing (12, 18) with a grip (14), in particular with a fixedly built-in battery (40), and with charging contact tongues (37) for charging the battery (40), is designed as especially compact and lightweight because instead of a boxlike, standard ON/OFF switch, counterpart contacts (34) fixed to the tool are provided, to which a contact plate (32) that is movable by means of an ON/OFF trigger (26) and in the process is coupleable to the counterpart contacts (34) and upon their release is easily releasable, is assigned.
