Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits

Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

End-of-life mercury-containing switches; automotive/industrial equipment decommissioning; MODERATE precious metal content (5-20% silver valuable); EXTREME hazmat complexity (mercury 30-70% HAZMAT CRITICAL; toxic bioaccumulative environmental contamination extreme; occupational exposure risk CRITICAL; EPA bans ongoing); LIMITED supplier base (234 suppliers; legacy equipment focus); LOWEST-TIER value commodity; mercury hazmat cost dominates; silver recovery offset by mercury disposal; hazardous waste specialist processing MANDATORY; environmental/occupational hazmat EXTREME; declining secular trend (mercury bans accelerating; alternative switches replacing mercury)

Acceptable Inclusions

Mercury 30-70% (switch specification; HAZMAT hazmat)
Silver 5-20% (valuable component; acceptable)
Steel/brass 15-40% (base metal; acceptable)
Plastic/ceramic 5-15% (insulation; inert)

Prohibited Materials

Mercury spill or switch rupture (hazmat spill; environmental catastrophe)
Unknown mercury content (hazmat uncertainty; risk unquantified)
Mixed mercury/non-mercury switches (contamination risk)
Intact switches without containment (handling hazard; occupational risk)
