Cap Height
For alternate action models

for cap removal. Indentations
on opposite sides of the cap
provide an easy way to lift
the cap out of the holder,
using either the finger nails,
or cap extractor AT109.
Overtightening the
mounting nut
may damage the
switch housing.

Note that the cap has a pair of
round tabs and a pair of long tabs
which should be used for correctly
replacing the cap in its holder.
Using the long tabs as guides, slide
the cap with the long tabs moving
into the slots on opposite sides of
the cap holder. Then, the round
tabs will snap into notches on the
other two sides of the holder.
