Hello I am based in the uk and work in the motor trade. I am after a good quality 4 channel remote and interface to go with it, if that's what you call it. The range of operation would be around 30 metre mark. It will operate some relays for a circuit we have. We want a reputable firm who can provide a good quality one with the type approval for the parts which is very important as we cant fit anything less. Would any of the suppliers also fit markings to our specification other than just A,B,C,D any help much appreciated.

Not quite my scene - I am unsure how far your "type approval" will affect the particular remote and its intended purpose. However, can I suggest that you use the universal guru - Google. I typed in "4 channel remote" and got what seems to be a goodly selection.

Hope this helps.
