Industrial Electric Automotive or Telecommunications Relay with Silver-Alloy Contacts
Electrical Component (Electromechanical Relay) · Unspecified industrial manufacturer (likely Panasonic, Omron, Bosch, or Finder); these are mass-produced technical components rather than decorative silverware.
Pattern: Multi-pin spade terminal relay design, standard industrial geometry used for switching high-current circuits.
Type
Electrical Component (Electromechanical Relay)
Maker
Unspecified industrial manufacturer (likely Panasonic, Omron, Bosch, or Finder); these are mass-produced technical components rather than decorative silverware.
Material
Contacts are typically Silver-Cadmium Oxide (AgCdO) or Silver-Tin Oxide (AgSnO2) for conductivity; terminals are nickel-plated brass; casing is flame-retardant translucent plastic.
Dimensions
Approximately 3cm x 4cm x 5cm; weight approx 50-80 grams. Not measured in troy ounces as it is not bullion or hollowware.
Description
This is a technical electromechanical relay, not a piece of decorative silver. While it contains valuable silver alloys within its internal contact points to ensure high electrical conductivity and resistance to welding during arcing, it is an industrial tool. The tarnish on the spade terminals is typical of 'industrial silver' used in electrical engineering.
Key Features
11-pin or 14-pin configuration; translucent amber casing; spade-style friction-fit terminals; internal mechanical armature.
Material & Composition
Contacts are typically Silver-Cadmium Oxide (AgCdO) or Silver-Tin Oxide (AgSnO2) for conductivity; terminals are nickel-plated brass; casing is flame-retardant translucent plastic.
Finish & Decoration
Industrial utilitarian finish; terminals show oxidation and heat-related tarnish from electrical arcing; no decorative engraving or aesthetic surface treatment.
Hallmarks & Stamps
No silversmith hallmarks; likely contains technical stamps on the top or side of the plastic casing indicating voltage (12V/24V/120V), amperage rating, and part numbers.
Construction Details
Machine-manufactured; plastic injection-molded housing with press-fit metal terminals and an internal copper electromagnetic coil.
Functional Features
Multi-pole switching; spade/lug terminals for plug-in connection; electromagnetic actuation to open or close electrical paths.
Handle & Grip Details
None; designed to be inserted into a socket or wiring harness. Plastic housing provides electrical insulation for handling.
Craftsmanship Details
Precision-engineered industrial assembly; focus on durability and electrical tolerances rather than hand-finishing or aesthetic beauty.
Authentication Indicators
Absence of silver hallmarks (lion passant, 925, etc.); presence of industrial spade connectors; plastic housing typical of modern electronics.
Origin & Manufacturing
Likely manufactured in China, Japan, or Germany in a high-volume electronics facility.
Era & Period
Late 20th to early 21st century industrial design (Contemporary).
Age Estimate
c. 1990-present day; based on the weathered plastic and tarnish, this appears to be a used vintage or salvage part.
Cultural Significance
Represents the shift from mechanical to electronic control in the 20th century; essential for the function of cars, elevators, and factory machines.
Condition Notes
Poor/Used condition. Significant oxidation on the metal terminals; dusty plastic housing; evidence of mechanical wear or salvage removal.
Value Estimate
$5 - $20 USD as a replacement part; scrap value of the silver content is negligible (pennies per unit).
Care & Maintenance
Clean terminals with electrical contact cleaner; do not use silver polish as the abrasive residues can cause electrical failure or shorts.
Similar Pieces
Potter & Brumfield relays, automotive fuse-box relays, or telecommunications switching crossbars.
Interesting Facts
Relays like this were the 'logic' of early automation before PLCs; the silver in these is highly prized by 'e-waste' recyclers who process thousands of them to reclaim the precious metal.
