FR Electronics

FR Electronics was a subsidiary of Flight Refuelling Ltd (now Cobham plc) that produced electronic components. This included reed keyboard switches. Cobham no longer have any record of these switches. Switch production was moved to Reed Relays and Electronics India Limited (RRE), a joint venture with FR Electronics that lasted for 20 years until FR Electronics left the market. RRE were able to supply some old stock illuminated switches (which they called RKS 80-1AL instead of RSM82-1AL) but they too have no details left on this product range.

Only one keyboard has ever been found with these switches, a 1988 Plessey Displays keyboard. The photos for this are all lost now, so it can no longer be examined for clues.
