Definitions
- the invention relates to an electrical switch with a switch housing, one on this mounted handle, one inside the switch housing arranged, locking recesses and having a guide the handle part coupled, guided by the guide link spring-loaded Curve follower, whereby by the interaction of the curve follower with the Guide link and their recesses the switch positions of the switch are defined.
- the invention provides an electrical switch in which the Switching noises are reduced and not due to their spectral composition attract attention.
- the guide link points to the Damping elements embedded damping elements made of elastic material on.
- the curve follower therefore does not bump, at least in the locking positions directly on the wall of the guide backdrop, since this is there through the stored damping elements is covered.
- the damping elements are preferably made of an elastomer material in two-component injection molding technology manufactured.
- the guide link is on one separate guide part formed with the switch housing through a layer is decoupled from elastic material. Since the switching noise on the Guide part have their origin is a damping of the coupling between Guide part and switch housing in the sense of further noise reduction very effective.
- the invention is particularly advantageous in the case of a rotary switch applied, especially in a light switch for vehicles.
- FIG. 1 A general belongs to the control unit of the electric rotary switch cylindrical region of a switch housing 10, one as a rotary lever formed grip part 12, which is non-rotatably on a coaxial in the switch housing 10 arranged switching shaft 14 is coupled, and a surrounding the handle member 12 and the open end of the switch housing 10 overlapping ring diaphragm 16.
- the Switch housings are two diametrically opposed guide pieces 18, 20 arranged from plastic.
- Each guide piece 18, 20 has in its inner circumferential surface, designated 18a in FIG. 2, with a guide link several guideways, which are designated in Figure 2 with 18b and 18c.
- the guideways 18b and 18c have a common section and two from this branched track sections at different heights.
- the control shaft 14 carries two diametrically opposite, radial Each cam carrier is loaded radially outwards by a compression spring Locking cams, 21 in Figure 1, which forms a curve follower and in the guideways the shifting gate of the guide part 18 arranged opposite or 20 is running.
- a compression spring Locking cams 21 in Figure 1
- the compression spring By the compression spring, the locking cam 21 against the wall of the Leadership backdrop pressed.
- the guideways are 18b, 18c of the guide link at the three provided at this switch Locking positions each with a locking recess in the one Damping element 22, 24, 26 is embedded from elastomer material. Furthermore, the Outer circumference of the guide parts 18, 20 with a damping layer 28 Provide elastomer material.
- the damping elements 22, 24, 26 and the Damping layer 28 with the guide part 18 and 20 in Two-component injection molding technology made of plastic.
- Wall parts are formed in the switch housing 10, between which the guide parts 18, 20 are inserted. A touch between them Wall parts and the guide parts only take place via the damping layer 28 instead of.
