Single open circuit. (J1.)
Transfer circuit. (J5).
Single closed. Isolated
switching “make”
circuit. (J4-1A).
JACK SCHEMATICS
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
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.
Double open circuit.
Isolated switching–
separate “break” and
make circuits (J2-1A-1B).
Double open circuit.
Isolated switching–
separate “make”
circuits on both tip and
ring. (J2-2A).
Single closed circuit,
sleeve common. (J3).
Tip closed, ring
open. (J10).
Double closed
circuit. (J7).
Single closed circuit
Isolated switching
“break” circuit. (J4-1B).
Double closed circuit.
Isolated switching
“make” circuit on ring
spring. (J7-1A).
DIMENSIONS ARE FOR REFERENCE ONLY
Single closed circuit. (J4).
Tip closed, ring open
(common to sleeve). (J6).
Single closed circuit.
Isolated switching
transfer circuit. (J4-1C).
Single closed circuit–
“make” before
“break”. (J8).
Single closed circuit
plus “make” before
“break”. Isolated
switching–“make”
before “break”
circuit. (J8-1D).
NOTE: Number indicates the quantity of circuit - 2-A means 2, A circuits.
Terminals locations shown on jack schematics do not necessarily coincide
with physical locations on jacks. Not all circuit types available on all jacks.
