Multi-Deck Rotary Switches

SERIES 71: PC Board Pattern In inches (and millimeters)

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.

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.

Electrical Ratings

Standard Style

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 MIL-

DTL-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-

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.

Additional Characteristics

Standard and Military Styles

Rotational Torque: 4-32 ounce-inches, (28-

230 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.

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

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

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.
