Wico Leaf Switch Arcade Joystick "Guard Actuator"

thingiverse

This is a part that attaches to the leaf switch on a Wico leaf switch arcade joystick. This one in particular is from a Simpsons arcade game, which I noticed was missing while I was rebuilding other parts of the joystick. I'm not aware of anyone that sells this part by itself, so I decided to design/print one. The purpose of it is to give the switch actuator (round plastic part that gets pushed into the switches) an even surface to press the leaf switch. The switch itself has the contact riveted through the metal, so without this, there will be an extra bump, which would eventually damage the switch actuator, and possibly cause poor control. According to the diagram, this is Wico Part Number 99-080033, or similar (looks slightly different than the one from the diagram). I believe that diagram is from an older model Wico Leaf Switch, so the part number may have changed... but it has the same/similar functionality. Instructions Print in your choice of plastic (I used ABS, since arcade games sometimes get pretty hot... especially during transport/storage). I believe the original plastic was nylon, which proabably has better wear resistance, but in a home environment, ABS should hold up just fine. The part is very thin (0.025" at the thinnest part), so I'd recommend a thin layer height. I printed at 0.25mm layer height, and the thinnest part was 3 layers thick. Once printed, simply press into the two holes on the leaf switch, on the side of the leaf switch without the extra metal reinforcement. Depending on your printer, you may need to use a knife to trim excess plastic from the pegs. Mine made a slight mess around the pegs, since it was printing plastic on top of the still molten previous layer (only took a few seconds to print those layers).
