Are you talking about an input selector switch ? If the RCA jacks are close to the switch, any wire is fine, single conductor hookup wire, even bare wire if it's short, like no more than 2 inches and the arrangement allows bare wires (they don't touch each other) You want to try to arrange the switch and jacks so everything is close for the shortest wires. Typically the switch on the front of the amp or preamp near the side, and the jacks on top or the side of the chassis, or even better, the jacks in the back, with the switch mounted near tha back on a bracket, with an extension shaft running to the knob on the front panel.
Gold contacts aren't that big a concern. A high quality switch will do it.
