So I'm guessing he has both mixed together. Alternatively, both switches COULD be 12VDC with a 110VAC relay with a 12VDC solenoid somewhere else in the TT that turns on the 110VAC. But even that "mixes" the 12VDC and the 110VAC on the same device.
And let's not forget the HWH has both 12VDC and the 110VAC stuff on it. In fact, the 12VDC and the 110VAC thermostats are side by side.
WHOA!!! wmtire doesn't have anything mixed. I'm just a messenger.
I was just showing pics of optional Suburban gas/propane panels and also of Turbs factory installed panel that has electric and propane switches in it. Any of my RV's have had the one DSI/propane switch inside and the electric heating element switch outside.
I believe we have discussed this before, and that BOTH the switches are 12 volt in these panels.....but the electric switch actually controls a 12 volt relay that turns on the 120 volt side.
Let me see if I can find this thread or a schematic to make sure I'm not dreaming it.
