Buy a cheap calculator or use a damaged keyboard to furnish
conductive pieces for repair.

Thanks to all. This is a largeish pad on a Drum Machine. I had a quick go
at slicing off part of the knackered pad and slicing off the conductive
nipple from a keyboard contact strip with a view to gluing some of them on.

Rapidly came to the conclusion I could not charge a customer money for a
complete bodge job I could not guarantee to work past next week. This is
the Start/Stop button which takes a hammering.

One more piece of old toot bites the dust.

I would have tried woven glass matt reinforced, moulded hotmelt glue sheet ,
with copper or brass gauze patches melted into the rear. Don't know how long
the pcb tracks would survive. Making the reinforced flexible sheet in my
tips files.
