Abstract : A switch actuator, for safe and arm applications requiring utmost dependability in order to preclude a premature or false arming sequence, utilizes a plurality of simultaneous input signals from independently coded pneumatic optical and electrical sources to drive a rotary switch. A rotary fluidic valving plate is used to decode non-uniform input optical signals into a uniform cyclical output pressure signal which is used to drive a fail-safe, reversible pneumatic piston type motor. A geneva mechanism is used to mechanically couple the prime mover to an output gear. (Author)
