I was having a devil of a time getting the horseshoe contacts adjusted on my Williams Disco Fever. Too tight and the target won’t drop – too loose and it won’t make contact. I thought this would be a perfect application for a reed switch. I dug around in my old parts stuff and came up with a bunch of reed switches and a perf-board. I found the magnets at Home Depot – almost perfect – just a little too thick. But they fit fine where the horseshoe contacts were. I hot glued a reed switch to the perf-board and tested – worked great. I finished it up with some old stuff I had laying around and installed the drop target. It works!!!
I’m really surprised someone doesn’t already make these.
