I had found an old thread once on a repair for the 3 little buttons when they stop working. I have no succes finding it again. Is there a reliable fix for these buttons ? If not could you point me in the direction of a supplier of replacement switches or buttons . On a side note has anyone wired in toggles to replace the buttons? Is my understanding correct that a 2 position toggle would be enough to replace the current set up . Any insight would be very helpful. Thanks to everyone in this great community for your help. Norm .
