Is it a single membrane switch or part of a panel. If single, chase down a similar type, if part of a panel you may be able to go back to the manufacturer for a replacement panel. Otherwise drill a hole and install a replacement unit being careful to

As part of the IPC-4552 specification testing, they ran ENIG at 2 uinches for 1.5 million cycles for a membrane-type keypad application [there was no testing for the wiping-type switches]. They stopped testing when the membrane began breaking down. T

I would agree with Doug, Enig with this type of switch is doubtful that it will hold up. You may have to think about Electroplated Deep Gold (hard Gold) 30-40 micro inches. Regards, Mike
