The loading of the leads and cable depends on the heat dissipation and has to be checked by testing.Gold-plated contacts are intended for use in signal circuits where the energy being switched is at the milliwatt level. Power being switched must be limited in order to avoid overheating and possible dispersal of the gold from the contact area.
