PCT No. PCT/DE95/00406 Sec. 371 Date Nov. 3, 1995 Sec. 102(e) Date Nov. 3, 1995 PCT Filed Mar. 24, 1995 PCT Pub. No. WO95/26589 PCT Pub. Date Oct. 5, 1995In known electrically operated handheld machine tools, a potentiometer serving to control output must be balanced so that a desired tap resistance can be tapped at the potentiometer in a determined adjustment position of the potentiometer. To reduce manufacturing expenses, this balancing is effected without required additional structural component parts or costly additional devices. The potentiometer (20) has a resistance path (21) with which a slider (22) is in electrically conducting contact by pressing. The slider (22) can be actuated manually by an actuating member (15). The slider (22) and actuating member (15) have means (26) for adjusting their relative position with respect to one another after their insertion into a housing (11) of the handheld machine tool.
