Abstract
A manually actuatable sliding short-stroke switch is provided with a light conducting cap attached to the sliding piece and a touch surface above the cap. A means for illuminating the touch surface is provided, and the light conducting cap is covered on its surface with a layer impermeable to light except for a selected area of the touch surface and a light instance area for receiving light from the source. The light conducting cap and the touch surface provide a means for actuating the switch substantially unaffected by fatigue due to repeated use and which can be illuminated without transferring light to adjacent touch surfaces.
