ABSTRACT:
The invention contemplates an improved flow switch providing an electrical output which is indicative of whether or not a predetermined flow or no-flow condition exists in an hydraulic line. In all its disclosed embodiments, the invention features simplicity of construction and a minimum of impedance to hydraulic flow, by reason of a straight-through flow alignment between inlet and outlet ports.
