Abstract
A mechanical pressure switch is provided which includes a conduit that is expandable and contractable in response to the pressure of fluid passing through the conduit. A switch is mounted in a fixed position relative to one portion of the conduit and an actuator is mounted in a fixed position relative to a second, spaced portion of the hose such that the switch will be mechanically activated and deactivated by movement of the actuator relative to the switch in response to pressure changes in the conduit. Preferably the relative positions of the actuator and switch are adjustable in the same direction as the expansion and contraction of the conduit.
