Replacing
a
Keyswitch
Board
Assembly
To install" a Keyswitch board assembly, insert the screws
in
the holes
in
the mounting bracket
on
the action assembly. Then slide
the Keyswitch board assembly down
-over the screws. Slightly
tighten the screws at the far ends first, then
the two screws
in
the
center.
Do
not
tighten the screws completely
at
first. Simply
tighten so
that
the assembly will slide up
or
down with slight
pressure. Align one side
.01
inch from the tab. Tighten and align the
otherside. Then align the middle of the assembly and tighten. This
should give a rough alignment. The longest leaf of the switch should
be
no
more than
.01
inch from the black tab
on
the action arm. The
longest leaf must be touching the bottom leaf, and you can visually
verify that this is correct by pressing a key and watching when it is
released
to
be
s~re
whether the bottom leaf moves when the longest
leaf returns.
