Claim:
In combination, a valve switch and a valve assembly comprising: a valve body, said valve body defining a conduit adapted for selective fluid flow communication between a source of water and a sprinkler system, said valve body including a valve member, said valve member being operatively connected to a rotatable lever for controlling fluid flow through said conduit; and a valve switch, said valve switch including a housing defining a chamber and having an aperture formed through said housing, said switch further including a plunger disposed in said chamber, said plunger being extendable through said aperture and operable between a raised position and an extended position, said plunger operatively associated with a contact arrangement for transmitting a signal when said plunger is placed in an extended position, wherein said lever is rotatable along a plane substantially similar to that of said plunger when said plunger is in said raised position to directly contact said plunger which maintains said plunger in the raised position and rotated out of contact with said plunger along said plane which forces said plunger into said extended position along a different plane.
