An optical sensor for detecting changes of state, which can be positioned inside a housing (2), which is in turn fixed in the operative position in the proximity of the change of state to be monitored. The sensor comprises a support (3) adapted to keep a stretch of optical fibre (F) in position, and a slider (4), which, in response to the change of state to be monitored, moves in such a way as to curve in a pre-set and controlled way the aforesaid stretch of optical fibre. |
