I haven't checked my suburban but i think the switch on the WH is also 12V switching a relay for the 120V.
BTW a friend had a brand new motor home where they had wired the switch to 120V rather than 12V and on walk through water heater was full, switched on the electric element and pretty quick smoke came rolling out. NOT a good thing.
here is a link to a typical suburban wiring diagram. Note NONE of the switches are 120V, they are ALL 12V.
