Rotary Switches
Multi-Deck Rotary Switches
SPECIFICATIONS
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
SPECIFICATIONS: Materials and Finishes
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.
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.

Electrical Ratings
General
Charts: Charts shown are for non-shorting
(break before make) contacts. Measurements
were made at 25°C and 68% relative humidity.
The load life curves show the number of
rotational cycles which can be expected for
the voltage, current and type of load. Thus,
for a standard style switch with a 300
milliampere 115 Vac resistive load, the
expected life is 15,000 cycles. Reducing the
load to 200 milliamperes increases the life to
25,000 cycles. Life limiting or failure criteria
are listed in the rating sections which follow.
Cycles: A cycle is a 360° rotation and a return
through all switch positions to the starting
position.
Voltage: As listed in charts.

circuit values: (also see standard style
description.) The Series 71 has been tested to
meet the requirements of MIL-DTL-3786, Style
SR39, the majority of which are listed here. At
85°C approximately 68% relative humidity and
sea level pressure, the switches have been
tested to make and break the following loads,
as stated in MIL-DTL-3786/39: 125
milliamperes at 28 Vdc resistive; 75
milliamperes at 115 Vac resistive.
The switches have also been tested at reduced
barometric pressure (70,000 feet), 25°C at
approximately 68% relative humidity to make
and break the following loads as stated in MIL-
DTL-3786/39: 50 milliamperes, 28 Vdc resistive;
20 milliamperes, 115 Vac resistive. When
tested to the above loads at stated conditions,
the Series 71 switches meet the following life-
limiting criteria after 25,000 cycles of operation
in accordance with MIL-DTL-3786/39.
Contact Resistance: 50 milliohms maximum
after life.
Insulation Resistance: 1,000 megohms
minimum between terminals and shaft.
Dielectric Strength: 500 Vac (atmospheric
pressure) and 350 Vac (reduced pressure)
between mutually insulated parts.
The Series 71 also meets the requirements
of MIL-DTL-3786/39 for moisture resistance,
stop strength, rotational torque, vibration (10
through 2,000 cps), medium and high shock,
salt spray, explosion, thermal shock (-65°C
to 85°C) and terminal pull. When tested at sea
level, 25°C and 68% relative humidity with
failure criteria of 50 milliohms maximum
contact resistance and 500 Vac breakdown
voltage, these switches will make and break
250 milliamps at 28 Vdc inductive (250
millihenries) 500 milliamps at 28 Vdc resistive:
500 milliamps at 115 volts Vac, 60 hertz
resistive, for 10,000 cycles of operation.

standard switches with either 1/8" or 1/4" diameter shafts
with either PC or solder lug terminals. It is not available in
military qualified or concentric shaft styles.
All dimensions, ratings and characteristics are the same as
the fixed stop equivalent. The chart shown here describes
the adjustable stop style substitutions for the fixed stop
styles. Although Series 71 is not an exact dimensional
equivalent of the fixed stop styles of Series 8 and 9, it most
nearly represents a functional substitution.

SHAFT AND PANEL SEAL
The shaft is sealed by an O-ring inside the bushing. The
panel is sealed by an O-ring at the base of the bushing.
The seals do not alter the dimensions as shown in the
drawings when the switch is mounted.
The panel seal is silicone rubber. The shaft seal is an O-ring
per MIL-P-5516B.

1/8" and 1/4" Diameter Shaft Switches
The bushing of the Series 71 switch is designed so the switch will not turn
if the panel has been cut to fit the exact bushing shape. The bushing for
the 1/8" diameter shaft switch has a double flat; the 1/4" diameter shaft
switch has a keyway in the bushing. An alternate means of keeping the
switches from turning is to mount them with optional, non-turn washers.
Part number 50J1066 is made of Stainless Steel. It is supplied with
military switches with Style A in the description. When ordered for
standard product, a like number of switches must be ordered.
