Raypack 006737F Pressure Switch 1.75 Psi

For my Raypak 407A - 006737F part number arrived in factory sealed plastic labled "Raypak Genuine Factory Parts" and was used to replace my original one marked "Barksdale The little general" labeled .5-5.0 PSI. I was a little worried about the big part number difference to old one, but it was exactly what I needed. Btw, before ordering I did (you should to) confirm it is this switch by jumpering the wires going to the switch, and when I did, the heater came right on, so unscrewed and replaced with this. Heater works perfectly now, no more invalid low pressure or clean your filter errors!

This cured my "water sw open" problem
