ABSTRACT:
Rotational switch, in particular gear box switches, comprising a housing carrying terminals (9), the housing being provided with fixed contacts (10) arranged concentrically with one another in two parallel planes (11,12), and a contact bridge (13) electrically connecting the fixed contacts (10), characterized in that, in each plane (11, 12) the fixed contacts (10) consist of at least one printed pattern (14) which patterns in each plane (11, 12) are sprayed on contact carriers (15) equipped with distancing pieces (17) and adapting elements (18). The contact carriers (15) cooperate with a contact module (16), and contact bridge (13) is held via spring loading in a switching member (22) which rotates in the housing (1). The contact bridge (13) thereby slides within the contact volume (2) formed by the distancing piece (17) of the contact carrier (15), over the exposed contact surfaces (21) of the printed pattern (14) which are oriented towards the contact volume (20).
The contact module (16) composed from the cooperating contact carriers (15) has an arcuate periphery with a frontal extension (25) which carries the terminal contacts (9). The distancing pieces (17) are located at the outermost arcuate path, at the lateral arcuate boundary (27) and in the vicinity of the frontal extension (25). The adapting elements (18) are formed on the distancing pieces (17).
