Seaflo pump pressure switch problem

[Notty1975]

Hi al I have a Seaflo pump 20L/min 60 psi with a accumulator tank now the pressure switches are melting I’ve had 3 of these switches under warranty with the 3rd fitted by a technician sent out to check pump, system, wiring etc with no fault found now this 3rd one has failed
My thinking now is the switch is not capable of carrying the current (9amp stated on pump) so was thinking of useing the switch as a switch for a relay thus minimum current through switch and relay taking a he main load
Do you think this will work
Thanks all

yes, good idea.. it's what I did with a Shurflo pump .. use a 12v 30A Auto relay
