| Oct 31, 2019 at 13:52 | comment | added | DKNguyen | @Bimpelrekkie well, gold is too expensive for most bows and in the old days silver was easier to work or stainless steel didnt exist, with and its density helps balance bows. but there are ways around that and we are past manufacturing difficulties with stainless stel | |

| Oct 31, 2019 at 13:48 | comment | added | DKNguyen | @AndrewMorton ye. gold is for dry switching because it doesnt oxidize to mess up weak signals. silver cadmium oxide is good at withstanding arc corrosion for higher currents. silver tin oxide is a run of the mill cheap non toxic material for intermediate | |
| Oct 31, 2019 at 13:48 | comment | added | Captainj2001 | Silver is good in a low/"no" oxygen environment. | |
| Oct 31, 2019 at 13:45 | comment | added | Andrew Morton | Apparently the minimum switching load for gold-plated contacts is lower than that for silver nickel, silver cadmium oxide and silver tin oxide ones in relays: Relay contact materials – does it matter? - if that is the sort of application you meant. | |

Really sucks because everyone uses silver on violin bows for prestige when stainless steel maintains a superior appearance for cheaper | |
