It would take me some time to find them, but I may have some 'spare' switches for these drives. of course they'll be old, so they may well ahev the same problems. Personally I would dismantly them. Most of the time the grease used in these sorts of switrches hardens withage, and you will not clean it out by soaking or sparying with solvent. You may well just move it elsewhere, like ont othe contacts ;-). I'vew dismantled many switches over the years, and unless there were plastic parts broken before I took them apart (the little rocker switches used for mains switching on some HP machines suffer from this), I've always got them back together again. As for solvents, I find the best thing to use to start with (in that it shifts grese and doesn;'t attack most plastics) is popan-2-ol. It's available from Mapiin in a 'Servisol' spray can. It's OK for cleaning the RK05 heads too :-) -tony
