Aren't 12 volt relays available? What is it about C4 that 120 volts is required?
Ernie, the OP stated that he would like to use a C4 Switch and has 120VAC available within the switch location. To me this means that the C4 switch requires 120VAC to work properly.
This then leads to requiring a relay that will be triggered using 120VAC, which is why I stated that this would not fit into a single gang box due to the combined size of switch and relay, this requiring to locate either device within a separate box that can be accessible and rated for 120VAC.
