[QUOTE="Vipersan, post: 847227, member: 325666"] Ok ..the basic principles of construction of the rotating magnate ..are good. I'm pleased with the result. It transpired I needed 4 x 2mm by 1mm magnets stacked per 'hotspot' in order to activate the reed.. and this works well enough.. BUT ..I may have another problem. Closer testing of the enclosed reed switch shows that it activates at either end ? ..not in the middle as expected. So ..it could be that there are in fact 2 reeds internally within the casing of what apears to be a single switch .. Possibly in parallel ..and activated ..not centrally ..but by 2 magnets simultaneously activated at a fixed distance between 2 magnetic hotspots...thus maintaining the count and behaving as one switch.... A sort of count failsafe. If this IS the case ..my replacement will not work as the spacing is different ..having increased the hotspots by 2 ..ie closer together. All that effort for nowt if this is the case. cest la vie. [/QUOTE]
