magnetic contact

thingiverse

magnetic contact a simple small holder for a magnet (Ø6 x 4mm). solder the cable to the magnet with some soldering grease. lead the cable through the hole and press the magnet in. please note: when soldering the wire, the magnet must not become too warm, otherwise it will demagnetize. first put a small drop of solder with soldering grease on the magnet - let it cool down - and then solder the wire. the best way is to position the magnet on a metal sheet or another magnet. another possibility, as a commentator recommends: do not solder to the magnet but to a small disc or ring - see picture. because of a possible disc, the cable routing was modified.
