Military equipment uses lots of, reliable, rugged slip ring assemblies. Maybe you can pick one up surplus. AST Servo Systems 1-800-922-1103 has a few in their catalog, from $26 to $200. Usually Slip ring assemblies use multiple contacts so if one bounces, the other(s) will still make contact. If you make your own, watch out for friction wearing down the brushes. You might want to use carbon brushes like from a car alternator or an electric motor. You could also optically or transformer couple the signals and power.
