Patent ID: 8746072

Claim:
A pressure switch comprising: a housing having a cavity for receiving a fluid, the pressure of which will be measured, the cavity extending from an inlet to an outlet and defining a flow path for the fluid, and a pressure-transducing element for measuring the fluid pressure, the pressure-transducing element being in fluid communication with the cavity and at least partially disposed in the flow path between the inlet and the outlet, wherein the pressure-transducing element has a cylindrical shape with a constant diameter, the pressure-transducing element is partially disposed in a bore in the housing, the bore having a constant bore diameter, one end of the pressure-transducing element extends into the flow path, and the pressure-transducing element is movable in the bore such that the pressure-transducing element is configured to move further into or further out of the flow path in response to a change in the pressure of the fluid in the flow path.
