Construction options
Choose the structure after defining the duty.
These categories describe how the rivet is built. They do not replace application testing or an approved customer specification.
01Solid contact rivets
A single contact-material construction for compact geometries where the complete rivet is specified in the selected alloy.
- Typical fit
- Fine-silver and selected alloy applications where conductivity, geometry, and switching duty support a solid construction.
02Bimetal contact rivets
A silver-alloy working layer combined with a conductive base material to place the functional material at the switching interface.
- Typical fit
- Common OEM choice when the contact face and the supporting rivet body have different material requirements.
03Trimetal contact rivets
A layered construction that can balance contact-surface performance, attachment needs, and efficient use of precious metal.
- Typical fit
- Made-to-drawing programmes where the working layer, body, and interface must be defined as one controlled part.
01Drawing
Head, shank, layer, length, tolerances, and controlled revision.
02Material
Preferred alloy and construction, or the data needed for review.
03Switching duty
Current, voltage, load type, operating cycle, and environment.
04Volume
Sample quantity, annual demand, packaging, and delivery target.
