Abstract: The invention relates to a battery-driven screwdriver comprising a housing (12, 18) provided with a handle (14), an on/off switch (26) and, particularly, a permanently fixed rechargeable battery (40) and charge contact tongues (37) which are associated with the rechargeable battery (40). The battery-driven screwdriver is characterised in that it is safe and comfortable to use due to the on/off switch (26) being mounted in a pivotable manner and extending in a longitudinal manner over the innerside of the handle (14), said on/off switch being able to be successively interrupted and/or closed, independently from each other, during the actuation stroke of several electric circuits of the battery-driven screwdriver (10).

Abstract: A power tool, in particular a cordless power tool, having a housing from which a tool emerges, with which tool a lighting device for a work field is associated, is made convenient to use because an LED serves as a light source, downstream of which is an optical light guide system, particularly with curved end faces, that collects the light from the LED and conducts it and aims it at a work field, and the LED and the light guide system are located in a light tube on the housing.
