Spacer decks can be supplied to facilitate PC board layouts of
three or more decks. A spacer deck does not have any
terminals and provides no switching function. Dimensionally, it
requires the same space as one normal switch deck. Spacer
deck can be placed at any location in the switch, per your
instructions. Switches which include spacer decks are procured
under a special part number.
Shown for a two deck switch.

Multi-Deck Rotary Switches
SPECIFICATIONS
Military Shaft and Panel Seal
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: nonturn 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.
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 nonturn 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.

SPECIFICATIONS: Electrical Ratings, Others
Electrical Ratings
General
Electrical Ratings
Standard Style
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.
Curves are based on the following failure
criteria:
Contact Resistance: 50 milliohms maximum
(20 milliohms initially).
Insulation Resistance: 1,000 megohms
minimum between terminals and shaft. (50,000
megohms initially).
Voltage Breakdown: 500 Vac minimum
between mutually insulated parts.
Current Rating: These switches will carry 4
amperes with a maximum contact temperature
rise of 20°C. If the life limiting characteristics
are less critical than those shown above, if
elevated temperatures or reduced pressures
are involved, Grayhill can predict the switch
life for the application.
Meet the Following Requirements of MILDTL-3786: Moisture Resistance: Medium and
High Shock; Vibration (10 to 2,000 cps);
Thermal Shock (-65°C to 85°C); Salt Spray,
Explosion; and Stop Strength (10 in-lb).

Qualified to the following MIL-DTL-3786/39
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 MILDTL-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 lifelimiting criteria after 25,000 cycles of operation
in accordance with MIL-DTL-3786/39.
Grayhill, Inc. • 561 Hillgrove Avenue • LaGrange, Illinois
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

500 milliamps at 115 volts Vac, 60 hertz
resistive, for 10,000 cycles of operation.
Additional Characteristics
Standard and Military Styles
Rotational Torque: 4-32 ounce-inches, (28230 N•mm) depending on the number of
poles per deck and the number of decks.
Contacts: Shorting or non-shorting wiping
contacts with over 100 grams of contact
force.
Shaft Flat Orientation: Opposite first position
pole no. 1 (See Circuit Diagrams).
Terminals: Switches are provided with full
circle of terminals regardless of the number
of active positions.
Extended Studs: Switches of 6 or more
decks (or concentric switches of 4 or more)
have longer studs and extra stud nuts for
recommended double end mounting. Stud
hole size is 1/16" diameter for #0-80 NF-2A
thread.
Stop Strength: 10 pound-inches.
Mounting Bushing Strength: 10 poundinches.

ADJUSTABLE STOPS
Set and Reset Stops to Limit Rotation
Form, Fit, Function Equivalent to Fixed Stop Styles
The adjustable stop Series 71 rotary switches allow you to
change the number of positions per pole. Simply remove
and relocate stop pins in the holes in the front of the switch.
The pins are held in place by a self adhesive sticker which
fits over the front plate.
This feature is available in the Series 71 single shaft
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
SHAFT “O” RING
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.

/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.
