Abstract
A medical instrument has a switch for controlling the operation of an external device operatively connected to the switch by way of a control section. The control section is a light transmitting section extending between a light source and a light receiver, and includes two optical fibers extending within the instrument with their ends in opposed spaced relationship. A cover plate is movable by means of a switch button, between the opposed ends of the fibers to alter the transmission of light to the light receiver at least in order to switch the external device on and off.
