Were can I buy ROBOT spares in the UK
 

Does anyone know where you can buy spare parts for Robot multiplexers in the
UK. I keep coming across ones with faulty front control buttons, although
the rubber conductive keys can be repaired it would be better to replace
them.
The repair agent ADT does not supply spares and charges a fortune for
repairs when it can do them and not loose the equipment.
Thanks for any info' in advance John.
