Electric switch, especially steering column switch for motor vehicles

Steering column switch with indirectly guided bridging contacts

Switch for energizing an electric motor of a wiper system

This invention relates to an electric switch, especially to a steering column switch. The switch comprises an insulation plate, a switch lever and a switching member, which are jointly swivellably mounted on the insulation plate in a swivelling plane extending perpendicular to a swivelling shaft and which are tiltable from this plane. In the swivelling plane, the lever and switching member can occupy several operating positions. The various operating positions are defined by a locking cam and a detent. One of these two elements is positioned on a locking lever. One end of said locking lever is swivellably mounted about a shaft parallel to the swivelling shaft of the switching member and the locking member is resiliently prestressed against the switching member. In order to prevent the switch lever and the switching member from shaking in the rest condition and to provide a smooth movement of the switch lever and switching member in a changeover between the operating positions, the switching member is guided in the swivelling plane by the switch lever. Thus, the guide can be maintained without an additional space requirement. Due to the guide, the switching member does not strike any other piece parts of the switch so that underside noise is also reduced.

Steering column switch

This invention relates to a steering column switch with two switch units arranged in superposed planes, which switch units each have a board with injection-moulded metal conductors and plug contacts the ends of which are rectangularly bent. The ends of the plug contacts of the switch unit which, in the plugging direction, is farther away from the connector, are positioned laterally of the ends of the other switch unit with a spacing from a conceived plane through the housing, which spacing is larger than the spacing of the ends of the plug contacts of the other switch unit from this plane. Thus a compact construction of the connection area of the switch is ensured.

Electric steering column switch for motor vehicles

In a steering column switch for motor vehicles a hazard-warning signal switch is clipped onto the printed circuit board of the turn-signal switch. The turn-signal switch is contacted at the upper side and the hazard-warning signal switch at the underside of the printed circuit board. The hazard-warning signal switch is compactly constructed and does not impede the movability of the other switch levers and switch slides of the steering column switch.

Steering column switch for motor vehicles

A steering column switch has two switching members superposed in a housing, which are swivellable about two parallel axes at least substantially diametrically opposite each other relative to a central aperture and tiltable perpendicularly to the swivelling plane. Two planar insulating plates provided with metal conductors stand perpendicularly on the swivelling plane. Each insulating plate has a free end formed as plug part and on one of these plates it is changed over when one switching member is tilted. To simplify the construction of the switch and to lower contact resistances switch contacts are also changed over on one of the two perpendicularly standing insulating plates with a tilting of the other switching member and with a swivelling of each of the two switching members.

A steering column switch for motor vehicles includes a support sleeve, which may be mounted on the end of a steering tube. The sleeve, between an internal collar integrally formed on it and a retaining ring is mounted a ball bearing for a steering spindle and which is made of plastics material. The retaining ring is separated from the support sleeve and held on it via the internal collar.
