An optical switch having a housing and optical fibers connectable to a light source and a light detector. The light source and light detector are located remote from the housing. The first and second light guide cables have distal ends positioned in a separator assembly and are optically aligned but separated by a gap. The switch includes a device to modify a light beam, and the device is usually adapted to removably occupy the gap. The switch may be embodied in a float.

1. A method of using an optical switch, were the optical switch comprises a housing, a first and second light guide, each having proximal and distal ends, said first light guide connected to a light source at said first light guide proximal end, said second light guide connected to a light detector
1. A method of using an optical switch, were the optical switch comprises a housing, a first and second light guide, each having proximal and distal ends, said first light guide connected to a light source at said first light guide proximal end, said second light guide connected to a light detector at said second light guide proximal end, said optical switch having a separator assembly, said distal ends of said first and second light guides positioned on said separator assembly, said separator assembly coupled to said optical switch whereby said separator assembly moves in response to movement of said housing, and said distal ends of said first and second light guides being separated by a gap, said optical switch further having a moveable member movable with respect to at least one of said distal ends between at least a first position A and a second position B, said distal ends being optically aligned in at least one of said first position A or said second position B, said housing being movable and said moveable member moving between said first position A and said second position B in response to movement of said housing, and said first and said second light guides bending between said distal and said proximal ends with movement of said housing; said method comprising the steps of transmitting light from said light source to said first light guide, and either detecting or not detecting a modified or unmodified characteristic of said transmitted light at said optical detector. 2. The method of claim 1 wherein said optical switch distal ends of said first and second light guides are substantially parallel. 3. The method of claim 2 wherein said optical switch distal ends of said first and second light guides are positioned side by side. 4. The method of claim 1 wherein said moveable member occupies said gap in one of said positions A or B, and said moveable member does not occupy said gap in the other of said positions A or B. 5. An optical switch comprising a housing, a first and second light guide, each having proximal and distal ends, said first light guide connectable to a light source at said first light guide proximal end, said second light guide connectable to a light detector at said second light guide proximal end, said optical switch having a separator assembly, said distal ends of said first and second light guides positioned on said separator assembly, said separator assembly coupled to said optical switch whereby said separator assembly moves in response to movement of said housing, and said distal ends of said first and second light guides being separated by a gap, said optical switch further having a moveable member movable with respect to at least one of said distal ends between at least a first position A and a second position B, said distal ends being optically aligned in at least one of said first position A or said second position B, said housing being movable and said moveable member moving between said first position A and said second position B in response to movement of said housing, whereby said first and said second light guides bend between said distal and said proximal ends with movement of said housing. 6. The optical switch of claim 5 wherein said housing has an interior, and said separator assembly is positioned in said housing interior. 7. The optical switch of claim 6 further having a means to modify a transmitted characteristic of a light beam wherein said means to modify a transmitted characteristic of a light beam modifies the amplitude, frequency or polarization of a light beam. 8. The optical switch of claim 6 wherein said housing is floatable in a desired fluid. 9. The optical switch of claim 6 further having a cable coupled to said housing. 10. The optical switch of claim 9 wherein said first and second light guides are contained within said cable between said proximal and distal ends. 11. The optical switch of claim 5 wherein said separator assembly further comprises a means to dampen said moveable member. 12. The optical switch of claim 10 wherein said cable comprises an outer sheath, an inner wrapping, and a filler material said filler material containing fluid paths through which air may flow, wherein said first and said second light guides contained ins said cable are contained within said filler material. 13. The optical switch of claim 6 wherein said separator assembly further comprises a paddle insert, said paddle insert having a top edge, side edge and bottom edge, a top portion and a bottom portion, said top portion of said paddle insert being free to flex in the interior of said housing. 14. An optical switch comprising a housing, a first and second light guide, each having proximal and distal ends, said first light guide connectable to a light source at said first light guide proximal end, said second light guide connectable to a light detector at said second light guide proximal end, said optical switch having a separator assembly, said distal ends of said first and second light guides positioned on said separator assembly, said separator assembly coupled to said optical switch whereby said separator assembly moves in response to movement of said housing, and said distal ends of said first and second light guides being separated, said optical switch further having a moveable member movable with respect to at least one of said distal ends between at least a first position A and a second position B, said distal ends being optically aligned in at least one of said first position A or said second position B, said housing being movable and said moveable member moving between said first position A and said second position B in response to movement of said housing, whereby said first and said second light guides bend between said distal and said proximal ends with movement of said housing. 15. The optical switch of claim 14 wherein said housing has an interior, and said separator assembly is partially positioned in said housing interior. 16. The optical switch of claim 15 wherein said moveable member further comprises a means to modify a transmitted characteristic of a light beam. 17. The optical switch of claim 14 wherein said housing is floatable in a desired fluid. 18. The optical switch of claim 14 further having a cable coupled to said housing. 19. The optical switch of claim 18 wherein said housing has an exterior surface and a indicia positioned on said exterior surface where said indicia is configured to allow a viewer viewing the housing to determine the orientation of said switch between said first position A and said second position B.
