Seeking new trinary switch for electric fan upgrade

[Rangergirl92]

Hey y'all,

I installed a new electric cooling fan system with a thermostat controlled activator. I am adding a relay into the system to help reduce electrical load, but also to incorporate a signal circuit from the A/C pressure switch.

I have a 1992 4.0L with the factory A/C installed. All components are new. I have a binary cycling switch.

I am looking for a good quality universal trinary 4 terminal (high/low pressure circuits, fan signal circuit, ground circuit) pressure switch I can use to replace the binary one so I can add the signal circuit to my relay harness. Needs to thread onto the standard schrader valve on the accumulator neck. Thanks in advance for your help and recommendations

I am trying to stay within the $15-$25 range if possible. Thx!

P.S. Links to products would be helpful.

I do not understand some of your terminology, but I think you are saying you want a pressure switch with multiple poles so you can run different circuits through the same switch?

Why can't you tie it all to the original switch using multiple relays? Split off the circuit after the original switch, and use that to trigger a bosch type relay. Use that relay to send power directly to the fans so they run all the time when the clutch on the A/C is pulled in.
