Optical switch of the multiple push button type for producing a plurality of control signals |
摘要 |
An optical switch of the multiple push button type for producing a plurality of control signals includes a housing and at least two sliders disposed within the housing. The sliders move between an initial position and at least two other positions. A pair of stationary light shields are disposed between said sliders in spaced apart relation, each of the shields having a plurality of apertures. Light emitting means are disposed between the stationary light shields. Separate light responsive means are disposed adjacent to each of the sliders. A pair of moveable light shields, each disposed between one of the stationary light shields and one of the light responsive means, each has a plurality of apertures and each is movable in response to movement of a separate one of the sliders. Circuitry responds to output of the light responsive means to produce the foregoing control signals, such output being dependent upon the position of the sliders.
