Just gone through the 'how to convert the switch to an iluminated' one in WIKI but got stuck on the resister, Do you re use the old diode with a new 75ohm resister ? if you do, does anybody know where you get the resisters from are they all the same ?
You can get them from RS electrical mail order, but don't know if you need to replace or fit the old diode?
