Abstract

An elongate contact switch is disclosed having several partial contact areas and associated illumination means for indicating the actuation mode and also the actuation point to an operator, in order to increase operational effectiveness. The illumination means can be directly associated with individual partial contact areas or can indicate the progress of movements for operating the contact switch by applying a finger and pulling the same along a contact area. Moreover, malfunctions can be indicated to the operator.
