摘要： A selectively aligned optical switching device including two adjacent translucent discs having mask segments formed on the surfaces thereof, with the first disc including a sleeve extending from the central opening thereof which is received within the central opening of the second disc. A clamping nut threadably engages the sleeve to selectively align the masking segments of the discs relative to each other. This combination of discs is clamped in concentric alignment against a timing hub which in turn is indexed by a pin relative to a rotary shaft. The mask section of the discs is then received in an optical coupling device which provides operating signals in selected coordination with the rotation of the shaft.
