ABSTRACT:
A fluid flow sensing switch device having a housing provided with a fluid flow passage therethrough defined by an inlet and an outlet separated by a valve seat controlled by a movable valve member that is operated by the pressure differential between the inlet and the outlet, the device having an electrical switch construction operatively associated with the valve member and having the switch contacts thereof actuated by the pressure differential. The switch contacts of the switch construction are disposed in the fluid flow passage so as to be exposed to fluid flow therethrough and have a part thereof carried by the valve member.
