<p>A fiber optic thermal switch is described comprising a first fixed fiber optic element (S) for transmitting light from a source of light, a second fixed fiber optic element (D) for transmitting light emitted from the first fiber optic element (S) and a snap-acting element (10), disposed between the ends of each fiber optic element (S, D), for interrupting the path of light flowing between the two fiber optic elements (S, D) in response to a change in temperature. In one specific embodiment, the snap-acting element (10) is in the form of a bimetallic disk (10) which changes its shape from a concave shape to a convex shape in response to a temperature change above a generally fixed transition temperature.</p> |
