<p>A transverse load sensitive optical treadle switch. The switch (20) includes a deformable longitudinal housing (44) and a fiber optic switch assembly positioned within the housing (44). The fiber optic assembly includes an optical fiber (22) having a first end and a second end, the optical fiber (22) being subject to bending upon application of a transverse load to said housing. Means for mounting the optical fiber (22) in the housing (44) so as to permit bending of the fiber (22) in response to application of a transverse load to said housing (44) are provided, the degree of bending sufficient to cause a significant decrease in passage of light through said fiber (22) when said fiber (22) is bent. Means permitting introduction of light into said optical fiber (22) at the first end of the optical fiber (22) and means for permitting the exit of light from the second end are also provided.</p> |
