i believe i have found a replacement switch for the delta and alpha but the shaft is a little short witch might be ok but its 0.250" (6.35mm ) D shaft and the arcams are 6mm D shaft and i need a shaft converter and i do not know were to look (in the uk).
its mainly for the alpha 9 as the knobs are all plastic were the delta 290 is metal with a plastic insert and if it come down to it i can buy a smaller knob and glue the old metal case on that.
