JACK SCHEMATICS
79
Circuit Types: Jacks normally have through circuits, shunt
circuits, and/or isolated switching circuits, either individually or
in various combinations. The chart below shows schematics of
39 common jacks - many more combinations are possible, but
these are the most commonly used. A basic description of the
switching action of each jack accompanies each schematic.
Military Identification: Military specifications covering phone
jacks use a special code to describe jack functions. Jack
schematic descriptions are coded J-1 through J-13 (as

One, SPST switching circuit. Also known as NO
(normally open) or “make” circuit.
One, SPST switching circuit. Also known as NC

One, SPDT switching circuit. Also known as transfer
or “break” before “make” circuit.
One, SPDT switching circuit. Also known as “make”
appropriate) to coincide with Federal Item Identification
Guides for Supply Cataloging. One or more groups of suffix
numbers/letters identify isolated switching circuits used.
Suffixes identify the switching by industry recognized notation,
i.e., 1-A, 1-B, 1-C, 1-D, etc. See chart below.
