ABSTRACT:
A fluid pressure actuator is disclosed of the type such as a hydraulic cylinder, having an arrangement for sensing the position of the piston and operating rod assembly at points within the cylinder. The sensing arrangement is disclosed as a magnetically biased reed switch which is installed within the cylinder pressure chamber so as to sense the proximity of the piston or a portion of the attached operating rod. Operating circuitry associated with each proximity switch is also disclosed which provides a delay feature preventing triggering of the associated circuitry upon momentary closing of the reed switch contacts due to mechanical vibrations or other causes.
