TL Series
TERMINAL CIRCUIT IDENTIFICATION
SPECIAL CIRCUITRIES
Terminal identifications 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).
Catalog listings with -10, -50, and -70 suffix numbers, as shown
in the order guides, have special “on-on-on” circuits, as illustrated
below. TLs with -12 suffix are the same as -50 except the keyway
position is maintained, and the center position circuits 2-3 and 4-5
are made. -72 is the same as -50 except that the opposite keyway
position is momentary, and in the center position circuits 2-3 and
4-5 are made.

IWTS provides a reliable, completely serviceable unit which meets
MIL-DTL-3950 requirements. IWTS improves maintainability 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 termi-
nals.
