An optical switch operatively sensitive to a fluid pressure differential includes a housing having an open end, a fiber optic input line, a fiber optic output line, and a fluid- proof diaphragm sealingly engaged with the housing. The diaphragm is formed from a thin elastic material resiliently stretchable between first and second switching states and supports an optical barrier within the housing for blocking the propagation of an optical signal between the fiber optic lines when the diaphragm is in one switching state and for permitting the propagation of the signal between the fiber optic lines when the diaphragm is in the other one of the switching states. For a given housing and a given diaphragm, different optical barriers may be employed to achieve different switching thresholds. As well differing optical barriers may be used to make the switch either a normally "on" switch or a normally "off" switch. Apparatus for monitoring the level of a liquid may include a plurality of such switches.
