ABSTRACT:
A universal valve switch for signaling the operative state of a valve assembly is disclosed that is attached to the body of the valve assembly using a bracketing arrangement. The valve switch comprises a housing defining a chamber and an aperture formed through the housing that communicates with the chamber. The valve switch may include a contact arrangement having a spring-loaded plunger that is extendable through the aperture with the plunger being operatively associated with the contact arrangement for selectively transmitting a signal to a remote panel whenever the lever is rotated out of contact with the plunger. In other embodiments, the contact arrangement may be replaced with various types of sensor assembly.
