Specifications

MII/STD-1472E
5.4.1 ,3.3 Location of Prim
MYcontrols. The most important and frequently used controls
(PticuladY rotary controls and those requiring fme settings) shall have the most favorable position for
ease of reaching and grasping.
5.4.1.3.4 Consistency.
The arrangement of functionally similar, or identical, prirnaty controls
shall be consistent fkom panel to panel throughout the system, equipment, or vehicle, e.g., a
movement of a control to the right or left should resuh in a corresponding movement of a displayed
element to the right or left.
5.4.1 .3.5 Remote controls. Controls, operated at a position remote fmm the display,
equipment, or controlled vehicle, shall be arranged to facilitate direction-of-movement consistency,
5.4.1.3.6 Maintenance and adjustment. In general, controls used sole!y for maintenance and
adjustment shall be covered during normal equipment operation, but shall be readily accessible and
visible to the maintenance tdmiciatt when required.
5.4.1.3.7 Spacing. Minimum sp~ing between controls shall comply with Table WI. Spacing
between a control and any adjacent obstruction shall be as shown by the figures referenced by Tabie
WI. Minimum spacing shown shall be increased for operation with gloves, mittens, or NBC
protective handwear, when such operation is a system requirement.
5.4.1.4 Coding.
5.4.1 .4.1 Methods and req
uirements. The use of a coding mode (e.g., size and color) for a
particularapplication shall be governed by the relative advantages and disadvantages of each type of
coding (see Tabk VIII). Where coding is used to differentiate among controls, application of the code
shall be uniform throughout the system.
5.4.1 .4.2 Locationadi.ng. Controls associated with sirnikr functions should be in the same
relative location from work station to work station and fmm panel to panel.
5.4.1.4.3
size’u3din&
No more than three different sizx shall be used to code controls for
discrhinati
on by absolute sire. Controls used for ptxfcmning the same function on different iterns of
equipment shall be the same size. WherI knob diameter is used as the coding parameter, differences
between diameters shall be not less than 13 mm (0.5 in). When knob thickness is the coding
parameter, differences between thicknesses shall be not less than 10 mm td.4 in).
5.4.1 .4.4 shape
-cod@ Shape coding, when used, shall ensure identification of control knobs
or handles by “fee!.” When shape coding is used
b. Shapes shall be identifiable by hand and by eye regardless of the position and
orientation of the control knob or handle.
c. Shapes shall be @c@allyiden@able when gloves must be worn.
d.

Chcmmmmort Sitzdi”tlenut rnorc”than ten.
e. Shape coded knobs and handles shall be positively and non-reversibly attached m their shafts
