ABSTRACT:
A fluid actuated switch including a fluid responsive vane pivotally mounted within a fluid directing channel is provided. The vane oscillates a movable electrical contact between two spaced stationary electrical contacts opening a first electrical circuit and enclosing a second electrical circuit as it moves from one stationary contact to the other. An adjustable holding assembly is associated with the vane for holding the movable switch contact into engagement with the stationary contacts such that a predetermined fluid force is required to move the vane opening one of the circuits and closing the other of the circuits.
