    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.
