Abstract
A miniature rotary multi-position switch capable of being mounted on a printed circuit board (2). The housing (1) and the rotor (8) of the rotary switch, are each provided with a throughgoing bore (33, 16). The rotating control shaft (17) is inserted into the bore (16) of the rotor (8), so that the shaft projects on one of the sides (3, 18) of the housing (1). This permits the rotary switch to be actuated from any optional side of the printed circuit board (2). Therefore, the printed circuit board (2) can be installed with one of its two plane sides facing the actuating side of an equipment unit, and the rotary switch can be nevertheless actuated in that the control shaft (17) is fitted accordingly. The rotary switch is mounted to the printed circuit board (2) by snap locks (5) and the rotor (8) is held inside the housing (1) with the aid of detent elements (10).
