Knob count.
Count all knobs (anything that twists). If it only moves up and down or left and right or in and out it is considered a switch and not counted). A
rotating lever
with more than two positions is a knob. For
concentric knobs
, count the number of independent twisting functions.
Count side controls
that can be adjusted using your fingers (no screwdriver adjustments).
