Sinclair DK Tronics Keyboard Switch Mount Adapter

I have a DK Tronics keyboard for a ZX Spedtrum. Three of the key switches were badly corroded. Unable to get replacements I have worked out a way of using new key switches and adapting them to work with the keyboard.

The old key switches need to be de-soldered. The new mount requires 0.8mm copper wire to create the leg and contacts.

There is also a post adapter that allows the DK Tronics keycaps to attach to the new key switch.

I'm not sure if this will work on all DK Tronics keyboards. I depends on the circuitry. On mine the ground circuit routes through the key switch itself.
