Avionics, Electronics & Interconnect
Connector Contacts, Terminals & Splices
BOLTON sources and supplies connector contacts, terminals, and splices for avionics, electronics, and interconnect assemblies across defence, aerospace, and industrial programmes. This family covers the discrete contacts that populate connector inserts, the ring, spade, and bullet terminals used at termination points, and the in-line splices that join or extend conductors.

Typical selection attributes
This page is a product family within the Avionics, Electronics & Interconnect pillar. It groups loose connector contacts, terminals, and splices as a category. The selection attributes above (contact size, termination, wire gauge, plating, contact type) act as filters within this family once the product table is populated, letting buyers narrow to a specific contact or terminal rather than describing a separate category.

Frequently asked questions
What is the difference between a crimp contact and a solder contact?
A crimp contact is mechanically attached to the conductor using a crimp tool, while a solder contact uses a soldered joint, typically at a solder cup. Termination type is a primary selection filter on this page because it affects tooling, rework, and the connector series the contact suits. Specify crimp or solder on your RFQ.
How do I identify the right contact size?
Contact size (such as 20, 16, or 12) is set by the connector insert arrangement and the wire gauge being terminated. Provide your connector series and wire gauge, or a manufacturer part number for identification, and we will match the contact against your build standard.
Why does plating finish matter for contacts and terminals?
Plating finish (for example gold, tin, or silver) is one of the selection attributes that influences conductivity, mating-cycle durability, and environmental suitability. Different programmes call out different finishes, so confirm the required plating on your RFQ rather than assuming a substitute.
Can you supply contacts to match a specific connector series?
We source and supply contacts, terminals, and splices and work from the connector series, insert arrangement, and line list you provide. Manufacturer and part-number references are used for identification and RFQ purposes only, not as a statement of compatibility or approval.
What information should I include when requesting a quote?
Include the connector series or insert arrangement, contact size and type (pin or socket), termination method, wire gauge range, required plating, quantity, and any manufacturer part number or drawing reference. The RFQ checklist on this page lists the full set.
