Publication number: 20110063817Abstract: A switch/circuit board unit and a hand-held tool equipped with such a switch/circuit board unit are proposed. The switch/circuit board unit is adapted for installation in a handle of the tool and has a switch and a circuit board. The switch/circuit board unit also has a mechanical coupling element for producing a rigid mechanical coupling between the switch and circuit board. The rigid coupling that the coupling element produces between the switch and circuit board allows the arrangement of the switch and circuit board to be embodied as a unit, which can enable maneuvering before installation and permit a simplified installation, and in particular, it is possible to simplify a fastening of the switch and circuit board inside a housing of the tool, and in the accompanying installation of electrical connections, for example in the form of flexible cables, it is possible to avoid an incorrect placement or wedging of cables.Type: ApplicationFiled: September 16, 2010Publication date: March 17, 2011Inventors: Andreas KYNAST, Markus Schmid
