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.

Steve,

This was my first installation of reed switches (Disco Fever). Over a year ago and they still work great - nothing to get dirty or ware out. I have since installed them on Blackout and Flash. The wiring on Blackout and Flash is slightly different from the Disco Fever. See this thread:

https://pinside.com/pinball/forum/topic/replacing-williams-drop-target-sliders-with-reed-switches

I had to use two reed switches on each target instead of just one. But they still work the same. On the Disco Fever and Blackout I mounted the switches horizontally. Later I found they work better mounted vertical. The adjustment is less critical. Keep in mind that the magnetic pull is greater on the sides of the magnet than in the center.

Hope this helps. Let us know how your's turns out.

Bob
