• The 2319 Controller is no longer available. If you have the pressure switched pictured in the image, you do not have to replace your pressure switch and you could purchase kit #7942 which does not come with the pressure switch.
• If you have the old style pressure switch that is longer and skinnier than the one pictured in the image, you will need to replace that switch, so this is the kit for you.
• The switch is approximately 1.75" in diameter.
