<p>An optical switch (2) comprising reflector means (12) which is movable from a first position to a second position and from the second position to the first position, the first position being one in which the reflector means (12) receives transmitted light and reflects it, and the second position being one in which the reflector means (12) does not reflect the transmitted light. The reflector means (12) may be mounted by a deformable optically clear medium. The optical switch (2) may include fibre optic means for the passage of transmitted light and reflected light.</p> |
