Abstract
In a switch, optical radiation from a radiation source 3 is supplied via photoconductor fibres 8, which are partially sheathed, to a radiation receiver 5 and is preferably manually acted upon. The photoconductor fibres 8 lie adjacent to one another on a contact surface 2 and the photoconductor fibres have no sheathing on the side lying opposite the points of contact of the photoconductor fibres with the contact surface. <IMAGE>
