Re: What is this??

Looks like a pressure switch for a water pump.

Not sure what it is but if it is a pressure switch for a water pump then the electric power to the water pump goes through the switch. The switch is connected in some way to water system supplied by that pump and when the water pressure reaches the set PSI the pump automatically shuts off so it doesn't burn up or over pressurize the system.

Well if it's a switch how would it regulate pressure, from the sensible explanations given it either turns the pressure on or off, but thanks for contributing Einstein.

When pressure drops below threshold it turns pump on, when pressure rises to threshold it turns pump off, ergo, it regulates pressure.
Your welcome.

I agree with what you say about working to a high or low pressure setting but regulate means to adjust, like a thermostat, a switch is either on/off.

Well I live and learn! Every fresh water pump I have owned has had the switch built into the pump itself. I didn't realise there were external versions. Good to know, thank you.
