This switch should work with any voltage within its stated range, either AC or DC. The mechanism is controlled by the water pressure applied and opens or closes the circuit accordingly.
Unfortunately this switch is not designed for your application.
The pressure switch works well,Just make sure the rubber is seal is secure,you will be ok. Here in Florida those little lizards are bad about getting in between the points and causing them not to connect.
It could be, but could also be: - No power (circuit breaker thrown, etc.) - Damaged wire or connection between pressure switch and pump - Pump failure With circuit tester/multimeter, check power at supply connection of switch. If no power, check circuit breaker or call electrician. If there is power, check pressure. If pressure is 40 psi or above, attach hose to pressure tank drain and open valve. If pressure drops and then pump starts as usual, then there is some plumbing issue between pressure tank and house. If pressure is below 40 psi, check power at pump connection of switch. If power to the pump is good, then there is a wire/connection issue between the switch and the pump or the pump itself is bad. If no power to the pump, then replace switch.
Before I would get a new pressure switch, you might want to take a air pump like a tire pump and add a little air into the tank and see if that will bring up your pressure.You can take a tire gauge and check the pressure. I would not go over 60 on the pressure gauge.
I don’t fully understand you question, so I would recommend calling us to assist at 844-251-7446. One thing to check: turn off the power to the pump, drain the tank, and check the air pressure in the tank. It should be set to 38 PSI of air for a 40/60 switch. If your tank is losing air, it could cause the inconsistencies and the tank may need to be replaced.
Any thing between 40 and 60 will work ok,I have mine set about 45.because I have a 40 gal tank,It really depends what size tank you have.The larger tank you might want it a litter higher, but do not go over 60.
I don't see any in mine all brass or copper besides the cover it is plastic
You should be able return it to the store for exchange.
probably need to sand off the contact points, to insure any corrosion on the contacts....
