I’ve been hunting down air supply leaks and found this.
It is at the top of the front air supply tank on the engine side.
It has 2-3/8” air lines, suspected switch at the top with wires.
I would like to know what it is and how to refer to it while looking for replacement part.

I think I have the same leaking pressure switch. Newell told me that the switch lights the dashboard light to indicate low air pressure.
I got a new one from Newell and will be replacing soon when I get under the coach to run some additional wiring in the same area.

Bingo, low air switch. Get one set at 60 psi.

Did you use soap water to find the leak?

Yes after my wanding with my infinicon “sniffer”
Alerted me to the leak. After repositioning to the back side of the drive axel I hosed all of the connections, hoses and parts up there and the switch had several leaks. Interesting my old ears could hear a leak, but I couldn’t locate it until I soaked it down. Then it started to gurgle, and was easy to find.
