Surfbeast Posted August 22, 2008 Report Share Posted August 22, 2008 What is the litttle cogged wheel that is on the back of my spa pack. I can bearly see it and the lettering is very small but it looks like it says "pressure". the wheel turns both ways, is this a pressure switch of some kind and if so what is it for??? Thanks!

1bad88 Posted August 25, 2008 Report Share Posted August 25, 2008 That is what my pressure switch looks like, it is a plastic cogged wheel in a sheet metal frame and has a black and red wire coming out of it. Quote Link to comment Share on other sites More sharing options...
