If it were mine, I would first try a spritz of contact cleaner into
the switch via the front panel slot (IIR465C). All contact
cleaners are the same - mineral oil and alcohol - so the cheapest
Radio Shack stuff works as well as anything. WD40 also works well.
==============================
On various occsasions I have been told that WD40 is NOT the right
cleaning agent for electrical systems involving plastic insulation re
wiring, etc. I always use (non chlorinated) contact cleaner as
available from Rat Shack and similar stores.
Here in the UK I use contact cleaner supplied by Maplin.

On TEK LF or HF cam style contact switches,do NOT use mineral oil-based
cleaner/lubes.Take some 99% isopropyl alco,wet a narrow paper strip,and
slide under the closed contact,and move back and forth.These cam-style
switches have VERY low wiping force,and any oil,grease,or film will cause
intermittents or opens.

I suspect a calibration may improve his triggering,too.
