5.4.3.1.6 Rocker switches.
5.4.3 .1.6.1 ~. Rwkcrswitches may& udinlieu oftoWlc switches for functions
requiring two discrete positions. They may be used for
applicationswhere toggleswitchhandle

forseparatelabelingof switchpositions. Rockerswitcheswith threepositionsshallbe usedonly
where the use of a rotary control, or legend switch control is not feasible or when the rocker switch is
of the spring-loaded center-off type.
5.4.3 .1.6.2 Accidental actuation. When accidental actuation must be prevented to avoid critical
or hazardous conditions, channel guards or equivalent protection shall be provided.
5.4.3 .1.6.3 Positive indication. An indication of control actuation shall be provided (e.g., snap
feel, audible click, associated or integral light).
5.4.3 .1.6.4 Dimensions, resistance, displacement and semmtion. Dimensions, resistance,
disphicexnentand separation between centers of rocker switches shall conform to the criteria in Figure
15. Resistance should gradually incmse, then drop when the switch snaps into position.
The switch shall not be capable of being stopped between positions.
5.4.3 .1.6.6 Orientation. Where practicable, rocker switches shall be vertically oriented.
Actuation of the upper wing shall turn the equipment or component on, cause the quantity to
increase, or cause the equipment of component to move forward, clockwise, to the right or up.
Horizontal orientation of rocker switches shall be employed only for compatibility with the controlled
function or equipment location.
5.4.3 .1.6.7 Color and illumination. Alternate colors may be used to denote the ON and OFF
portions of a rocker switch. Alternate illumination of either the ON or OFF switch position
may be
used to facilitate positive recognition of current switch position. For other color coding, see
5.2.2.1.18. Where ambient illumination will provide display luminance be~ow 3.5 cd/m2 (1Ft-L), the
rocker switch should be in-y ihnimd.
Digitarlnd letters ahauappear asiuuminatdcMMw
on an opaque background and their dimensions should approximate the following:
a. Height: 4.8 mm (3/16“)
b. Height-to-Width Ratio: 3:2
c. Height-to-Stroke-Width Ratio: 10:1

5.4.3 .1.7.1 ~. Slide switch controls maybe used for functions which require two discrete
positions. Slide switch controls may also be used for functions which require a higher number of
discrete positions in which the switches are arranged in a matrix to permit easy recognition of relative
switch settings (e.g., audio settings across frequencies), but shaI1not be used where mispositioning is
to bc avoided.
