Abstract
Abstract A steering column switch for motor vehicles includes a switch housing and a switch lever mounted therein which may be pivoted about an axis together with a switching member, which switch lever is provided with at least one read-out panel which may be illuminated by a light guide traversing the switch lever, which light guide is aligned with a light source by a light-input area. The light source is fitted and protected in the switch housing; it is free from hard switching-on and switching-off impacts of the switch lever. In particular, it is arranged centrally around the pivotal axis of the switch lever and switching member, so that it is possible to illuminate the read-out panel with the same intensity in all switching positions of the switch lever relative to the pivotal axis.
