Thanks to hallo_ralph for the original design. I had only magnets with dia 5 x 2mm around, this is the adaption for these magnets. If you have to order the magnets, order the larger dia 6x4mm ones. The dia 5x2 work, but the adhesion force is not too big.
Take care about the orientation of the magnets. They should reject each other when the blank contact sides are pushed together. Otherwise they might make -with sparkles- magnetic contact and shorten the power supply.
