SHAFT AND PANEL SEAL: Srs. 42 & 44 Standard Style
The Series 42/44 Styles, which include the letter "S" with the exception of style "HS", are watertight sealed to the mounting panel by utilizing the panel seal kit. These switches are built with a front plate that does not have a non-turn tab. The panel seal kit consists of a grooved hex nut, a keyed washer and a keyed panel seal. The grooved hex nut is assembled to the switch bushing. The keyed washer is slid down the bushing slot and seated into the hex nut groove. The seal is likewise assembled to the bushing and hex nut. The keyed washer is required to provide seal integrity in the bushing slot. When assembled to the panel, the grooved nut, backing washer and seal require the same space as a normal mounting nut. Hence, the seal kit does not alter the dimensions. Panel seal kit includes a non-turn washer to be used into a blind hole in the back panel. For panel seal kit part dimensions, see Accessories. Style "HS" switches use a similar sealing method, except the integral assembly nut retains the panel seal. All sealed style switches are provided with a shaft to bushing internal seal.

ADJUSTABLE STOP SWITCHES: Series 42 and 44
The standard and UL recognized switches are also available with adjustable stops. Two removable stop washers allow you to limit the number of switch positions as needed. A knurled nut is supplied to secure the washers if desired. These switches have no bushing keyway. All other dimensions, ratings and characteristics are the same as the standard fixed stop styles. Although not military qualified, the adjustable styles are useful in military equipment prototypes. However, when submitting the equipment for government approval, the fixed stop qualified style should be substituted. See additional adjustable stop switch information at the beginning of the Rotary Switch section. For ordering information, see page J-60. Front Views

Multi-Deck Rotary Switches
MILITARY QUALIFIED
Single Shaft Switches
The military styles of the single shaft Series 42 and 44 rotary switches are qualified to MIL-S3786/4, specifically SR04-1. Qualification includes two temperature ranges. Unsealed styles M, MB, MG and MBG are qualified for -65 to 85C. Unsealed styles H, HB, HG and HBG, plus sealed styles HS, HBS, HGS and HBGS are qualified for -65C to 125C. Qualification includes low level switching and shaft grounding as specified in MIL-S-3786. Qualification includes 30, 36, 45, 60 and 90 angles of throw with solder lug terminals. The military styles are dimensionally the same as the standard styles with two exceptions. The location of the common for the 3-pole switch differs (see circuit diagrams) and the non-turn tab for styles HS, HBS, HGS and HBGS differs per the Shaft and Panel Seal description following.
specifically SR04-2. Unsealed switches are qualified for -65C to 85C in 30, 36, 45, 60 and 90 throws. The standard and military styles of the concentric switches have the same dimensions with the exception of the location of the 3 pole common (see circuit diagrams). The 30 and 36 throws are described in the ordering information. If the 45, 60 and 90 throws are required, they can be provided in Section A of the Series 54 Rotary Switches; see Standard Options, page J-9.
following pages. Standard variations such as terminals, shaft and/or bushing length etc., which do not affect performance, can be marked as qualified product. Adjustable stops cannot be qualified. Contact Grayhill for details about variations. Military qualified switches may be ordered by the military M number listed in MIL-S-3786/4 or by the Grayhill part number. They will be marked to specifications.
Add-A-Pot Switches
The military style of the add-a-pot Series 54 switch is qualified to MIL-S-37864, specifically SR04-3. These unsealed switches are qualified for -65C to 85C in 30, 45, 60 and 90 throws. The dimensions of the military style add-a-pot switches are not the same as the standard adda-pot switches; see drawings.
MILITARY QUALIFIED SHAFT AND PANEL SEAL:
Styles HS, HBS, HGS and HBGS
The shaft is sealed to the bushing by an internal O-ring per MIL-P-5516B. The bushing is sealed to the panel with a silicone rubber washer and a stainless steel backing washer. The combined uncompressed thickness is 0.055" (1,40). Since this switch has a flat cover, a non-turn washer is supplied (see Panel Seal Kit). If using it, mount it in front of the panel. For Panel Seal Kit, see pages J-60.
Two Switches, Concentric Shafts
The M style of the concentric shaft Series 43 and 54 switches is qualified to MIL-S-3786/4,

Rating based on the following criteria: Overload: 50 operations at 150% rated AC load Endurance: 6000 operations at the rated load with 1000 Vac dielectric strength before and after test Temperature Rise: Not to exceed 30C when carrying rated AC load after test. Note: all dimensional drawings for the standard style Series 42, 43, 44 and 54 also apply to these switches, with the exception that switches are marked per specifications.
before make) Voltage and Load: As listed in the chart One cycle is 360 rotation and a return through all switch positions to the starting position. The data for the curves was measured at sea level, 25C and 68% relative humidity. The Series 42, 43, 44 and 54, style M, H and HS switches are made to meet requirements of MIL-S-3786, style SR04. Diallyl phthalate molded parts and the design of internal switching elements provide exceptional performance. Curves shown are typical load-life curves for Series 42, 43, 44 and 54, style M, H and HS switches with 30 or 36 angles of throw. They show the numbers of cycles of rotational life expectancy for the types of loads shown. Thus, with a 5 amp, 115 Vac resistive load, 10,000 cycles of life is expected. If the load is reduced to 3 amps, life is increased to 25,000 cycles. The larger angles of throw (45, 60 or 90) switch larger currents for a like number of cycles. Life limiting or failure criteria for these curves are: Contact Resistance: 50 milliohms maximum Insulation Resistance: 1,000 megaohms minimum between mutually insulated parts Voltage Breakdown: 1,000 Vac minimum between mutually insulated parts. These switches will carry 10 amps with maximum contact temperature rise of 20C. Life can be predicted by Grayhill if less critical life characteristics, elevated temperature or reduced pressure is involved.

Contact Resistance: 50 milliohms maximum Insulation Resistance: 1,000 megaohms minimum Voltage Breakdown: 1,000 Vac initially (500 Vac or better after most environmental tests) Life Expectancy: 100,000 mechanical cycles of operation. Note: Actual life is determined by a number of factors, including electrical loading, rate of rotation and environment, as well as maximum voltage breakdown required at the end of life.

Specify fixed stop or continuous rotation when ordering single shaft switches. Concentric shaft switches have continuous
rotation. 4 Styles which include both M and S are not qualified but are made of the same materials and construction as qualified types. For qualified switches with shaft and panel seal, use equivalent HS style. 5 UM switches are made of the same materials and construction as the M style switches. For military switch UM is not required; use M style.
