Military Qualification MIL-DTL-3786/39
The military style of the Series 71 rotary switch
is qualified to MIL-DTL-3786/39. Complete
electrical rating information is listed on the
following page. The Series 71 rotary switch
qualification includes the 30° and the 36° angles
of throw, in .125" (3,18) and .250" (6,35)
diameter shafts, with solder lug terminals and
printed circuit terminals, in sealed and unsealed
style switches. Standard variations such as
shaft and/or bushing length, etc. that do not
affect the switch performance can also be
marked as qualified product. Contact Grayhill
for complete details.
Dimensionally the military style is the same as
the standard style with the exception of the PC
version of 3 or 4 decks; a spacer deck between
decks 2 and 3 adds another deck length to the

switch without increasing the number of operative
decks.
Another difference in the standard and military
styles is the mounting hardware. Ordered as
options with a standard style switch these items
are included with the military style switch: non-
turn washer with solder lug style and a non-turn
washer plus a mounting bushing washer with
the PC terminal style.
Complete specification drawings are available
from Grayhill, Inc. for the standard military
qualified products. Military qualified Series 71
rotary switches may be ordered by the “M”
number listed in Military Specification Sheet/39
or by Grayhill part number. All qualified switches
will be marked to the specification.
Mounting Hardware: One mounting nut and
one internal tooth lockwasher are supplied with
each switch. For switches with A in the style
description, the nut is .062" (1,57) thick by
.312" (7,92) across flats. For switches with B or
C in the style description, the nut is .094" (2,39)
thick by .562" (14,27) across flats. Nuts are
brass, tin/zinc-plated or stainless steel.

Military Shaft and Panel Seal
A shaft and panel seal is available to provide
watertight mounting of the Series 71 standard
military style rotary switches. Sealing is
accomplished by an O-ring shaft seal and a
panel seal washer. Panel seal dimension
differences are shown in the dimensional
drawings. When the panel seal is compressed,
dimensions are approximately the same as an
unsealed switch. If the non-turn washer
supplied with the switch is used, it should not
be allowed to extend entirely through the
panel when mounting a sealed switch.
However, the bushing may be used as a non-
turn device instead. Switches are provided
with a double flat bushing in styles which
include the letter A and with a bushing which
has a keyway in the styles which include the
letter B.
Detent Rotor: Phenolic per (MIL-M-14)
ASTM-D-5948
Mounting Hardware: One mounting nut and
one internal tooth lockwasher are supplied
with each Series 71 switch. For switches with
Style A in the description, the nut is .062"
(1,57) thick by .312" (7,92) across flats. For
switches with Style B or C in the description,
the nut is .094" (2,39) thick by .562" (14,27)
across flats. Nuts are brass, tin/zinc-plated or
stainless steel.
Additional Hardware: Each switch is
supplied with a non-turn washer to use if
desired. Additionally, each PC mount switch
is supplied with a mounting bushing washer
(see PC Mount Accessory). For switches
with Style A in the description, non-turn
washer is stainless steel; for switches with
Style B in the description, non-turn washer is
stainless steel. Mounting bushing washer
(PC Mount Accessory) is brass, tin/zinc-
plated.
