All my contact switches on the KLM-614 seem to be non functional, I de-soldered a few of them, checked continuity between contacts but they don't work, tried to pull them apart to clean but it seems impossible.
I tried sourcing the Fujisoku TM1 switches but they seem to be either non existing or too expensive.
I'm thinking of maybe laying out a new board with illuminated switches unless I can find an alternative pushbutton tact switch.
any info appreciated
thx
