Perfect fit, Perfect function.
Perfect fit for my Northstar Hot Water Pressure Heater model 157226a, part number 30529 (which is NLA). Fixed my 30 year old tool.

Good Quality
Identical to the flow switch on my Northern hot water electric pressure washer. The pressure washer had sat for several years, unused. The pump worked but the burner wouldn't turn on. Customer service suggested cleaning the flow switch. Amazon warehouse had one for a good price so I bought and installed it. The switch and cord are of good quality and has the correct terminals to hook directly into the Northern Machine.
