Drawn to true relative scale — the variants above are directly size-comparable.
Silver contacts (switches, breakers, contactors)
White all the way through, and non-magnetic. Silver is bright white, not yellowish like brass, and won't take a magnet. A file cut showing copper underneath means plated, not solid. Aged solid silver goes dark grey or black from sulphide — still fully valuable. Green corrosion means copper, not silver.
How to spot it
Riveted or brazed buttons and pads of bright white metal on copper or brass arms, inside contactors, breakers, thermostats, knife switches and large switches. Alloys in circulation: fine Ag, AgCdO (85–90%), AgNi 90/10, AgSnO₂ (88–92%), AgW (25–50%), Ag-graphite. Some are stamped Ag or with an alloy code.
Metal content
| Metal | Quantity | Notes |
|---|---|---|
| Silver | 180–400 g/lb of clean cut contacts | contact buttons are 40–90 wt% silver |
At 4 Aug 2026 spot prices that works out to $532 per pound of contained metal — Silver 280 g = $532. A refiner paying $420 returns about 79% of that, which is normal: refining costs money and the buyer takes a margin.
Safe removal
Working temperature: Cold — side cutters
Snip the button off the carrier arm with side cutters and keep the copper separately. Keep contacts dry, weigh before shipping, and never mix them with gold-plated or copper scrap — mixed lots get assayed down.
Hazards
NEVER grind, burn, torch or braze cadmium-plated or AgCdO material, and don't inhale the black contact dust.
