Now I have a new way to drive the people in my local appliance parts store nuts! They can never figure out why I am often there looking through the various heaters, switches, and sensors hanging on the wall. They really hate when I ask them if they can get a sensor like the one I saw in a thig-a-ma-jig... he he :) BTW, this sounds like a good idea. Are they really inexpensive? when I last checked the cost of a low pressure switch for my Sears water softener tank, I quickly decided it wasn't worth fixing with the original type part...
