RE: Questions about interior LED? #2

QFOM is the quattro faq-o-matic run by Brett Dikeman.  The URL is:


I have found that one needs two items to open these swiches.  First, a
jewelers screw driver with which to pry the shell near the pins, and second
a set of shims (I use 0.010 nickel shim stock) cut to about 1/8 inch by 1
inch to block the internal plastic tangs from protruding into the outer
shell.  It is also necessary to pry off the lever control so one can see the
ends of the inner plastic assembly.  This is done by determining which side
of the pivot is tapered and capable of being angulated out first.  Once the
shims are in place, the inner assembly extensions below the lever are pushed
upon to start the guts out of the rear of the switch.
