Pressure Switch 3029P 25A Tecmark 1/8"mpt SPNO Plastic Body

You are buying a Techmark 4000 Series 25Amp Pressure Switch with a Plastic Bottom and top that features 1/8th" MPT Standard Threads and 2 Spade connectors for attaching the 2 wire connections. This Switch will fit Balboa, Gecko, ACC, Hydroquip, Len Gordon, Maddux and most other standard Hot Tub Heater Tubes but the 25Amp feature is rarely found. The 25Amp switch would normally be found in a 115V Plugged in stsyle where the hot wire for the Heater runs through the switch. Most Air Button Pressure Switches only have a relay turn on wire going through the Pressure Switch that draws less than 1 Amp. What goes wrong with these switches is either the Switch does not close when the pump comes on and puts pressure on the switch or it doesn't open when the pump goes off. If either of these things happens you will have a No Heat or Overheat Situation on most systems. The are other things that will cause a flo code like an inoperative pump or a stopped up filter so be sure the switch is bad before replacing. The Pressure Switch in this auction will work in any application including a 25 Amp or a 1 Amp system where a 1 Amp will on work in a 1 Amp system that application. We have plenty of these.
