I can answer my own question but throw up another, it is not that simple of style switch it is part of a long brass shaft which runs through the band trimming under a removable grey plate, now the switch is more in view it is not a simple replacing switch, which makes me go back to what I first thought when I opened the case on initial inspection I found two ball bearings loose inside obviously from this switch which clicked it in place. I presume two ball bearings as this is what I found inside am I correct in thinking they somehow fit under the grey silver bit in the photo on the rotor of the switch if so it could be possible to slot two new ones back in?? finally which others and I have experienced the one big gripe I have against Eddystone is again on this model the four impossible brass screws used to fix the panel to the chassis...I won't even try
