WIRE-WRAPPING TERMINATIONS
Switchcraft can build complete Jack Panel Assemblies with
WIRE-WRAPPING CONNECTIONS

terminals can be installed in the same assembly.
WIRE-WRAPPING TERMINAL DESIGN
Jack springs with integral wire-wrapping terminals are made of
special copper alloy for maximum work-life with excellent
resistance to corrosion. Shank of terminal accommodates a
maximum of three wire connections. Tini-Telephone ? phone
jacks, lamp jacks and switches with wire-wrapping terminals
have slightly higher stack due to greater spacing required for
