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.

Multi-Deck Rotary Switches
SPECIFICATIONS
Military Qualification MIL-DTL3786/39
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
will be marked to the specification.
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
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.

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). Electrical Ratings
Military Style
Curves are based on the following failure
criteria: 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 MIL-DTL3786/39: 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. 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.

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 StANDARD
load, the expected life is 15,000
cycles. Reducing the load to 200 milliamperes
increases the
to 25,000 cycles. Life limiting

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.

SHAFT AND PANEL SEAL
SHAFT“O”RING
PANELSEAL
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.

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.
