Flexible switch apparatus and method for making same

A switch apparatus includes a carrier for an optical cable. The carrier supports the optical cable in a U-shaped configuration with parallel leg portions of the optical cable extending along opposite sides of the carrier. A pushbutton is supported by the optical cable. The pushbutton has actuation arms which engage the parallel leg portions of the optical cable. The optical cable is held by flexible arms which form channels into which the leg portions of the optical cable are snapped. Upon manual actuation of the pushbutton, the optical cable is deformed to reduce the intensity of a light beam transmitted through the optical cable.

Switch apparatus

An improved switch includes two moving contact members which move in parallel planes. The switch may be moved to either of two positions to complete either of two circuits. The contact members are normally biased to a central neutral position. Since the contact members move in a plane, rather than pivoting on a yoke, there is greater tolerance in positioning the moving contact members.
