TERMINAL CIRCUIT IDENTIFICATION
Terminal identifications are referred to in the order guides to
indicate which circuits are made in each toggle position (i.e.,
12 refers to circuit closure through terminals 1 and 2).
One Pole Two Pole
TERMINALS
In addition to the solder terminal listings in the order guides,
IWTS (Integrated Wire Termination System) and quick connec-
tion versions 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-ex-
tract 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 MS39029/1101 contact pins. Connections
are resistant to shock, vibration, and high pull-out force.
