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 300milliampere 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.

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. (50,000megohms initially).

Voltage Breakdown: 500 Vac minimum between mutually insulated parts.

Current Rating: These switches will carry 4amperes 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-3786/39circuit 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: 125milliamperes at 28 Vdc resistive; 75milliamperes 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 (10through 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 (250millihenries) 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
