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.

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. 50 Grayhill, Inc. • 561 Hillgrove Avenue • LaGrange, Illinois 60525-5997 • USA • Phone: 708-354-1040 • Fax: 708-354-2820 • www.grayhill.com Rotary Switches CURRENT CURRENT CURRENT CURRENT MILLIAMPS MILLIAMPS MILLIAMPS MILLIAMPS CURRENT CURRENT CURRENT CURRENT MILLIAMPS MILLIAMPS MILLIAMPS MILLIAMPS CURRENT CURRENT MILLIAMPS MILLIAMPS Charts: Charts shown are for non-shorting (break before make) contacts.

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. STOP PIN HOLES STOP PINS STICKER 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.

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. .625 ± .010 DIA. (15,89 ± 0,25) Part number 50J1066 is made of Stainless Steel.
