[Techtoolslist] Fluke 9020a - need replacement "low pulse" key switch

[Andy Smout]

hello! I recently bought a Fluke 9020a w ieee-488 interface
and the "low pulse" key switch behaves as a momentary sw only
whereas the "high pulse" switch is a toggle - PTMK-PTBRK.

on reading a post by Martin from 2006 i realised my LOW pulse"
sw probably needs replacement. anyone know of a source for the
switch mechanism ?

anyone repaired or lubricated the switch successfully ?

cheers, andy
