TERMINAL CIRCUIT IDENTIFICATION
Terminal identications are referred to in the order guides to indi-
cate which circuits are made in each toggle position (i.e., 1-2 refers
to circuit closure through terminals 1 and 2).

TERMINALS
In addition to the solder terminal listings in the order guides, IWTS
(Integrated Wire Termination System) and quick connection ver-
sions are also available.
IWTS provides a reliable, serviceable unit and promotes main-
tainability since wiring bundles need not be disturbed. Leads are
quickly and easily assembled or removed with an insert-extract
tool. A unique three-rib (grommet style) elastomer seal protects
the lead connections without potting. There are no exposed metal
terminals. Versions available that will accept No. 20 wire with
MS39029/1-101 contact pins. Connections are resistant to shock,
vibration, and high pull-out force.
