Abstract
An optical switch (10) includes a light input (12a), a plurality of light outputs (12b) and at least one light pathway movable from a first position where a light communication path is formed between a light input (14a) and a first light output (14b) and a second position where a light communication path is formed between the light input and a plurality of light outputs. Multiple light pathways are configured within the switch and selectable by rotation of a switch housing part enabling sequential selection of light communication paths. The switch can be used on a surgical device to control illumination of the surgical field during a procedure.
