Very interesting, our switching maven says. This brand new, air-pressure-activated switch made for a Sears well pump has a DPST normally-closed relay, which is nominally rated for 40psi cut-on and 60psi cut-off, but can be adjusted with (2) internal screws. The air inlet is 1/4" -18 NPT female (7/16" ID). The switch contacts are rated for 20A at 115V and 12A at 230V, 1.5 and 2 hp, respectively. The unit measures 2-5/8" x 3-15/16" X 2-1/2" OA, not counting the NPT fitting, and has (2) 7/8" ID bores opposite each other. UL/CSA.
