Adding these is a non-permanent change to allow you to open the coin door on a game without killing high power. Essential for tournaments where you might have to release a stuck ball without dropping the flippers. The old version didn't fit my games, so I made a few new ones:

• WPC interlock clip: Fit on my Twilight Zone with the single interlock switch
• SAM JJP interlock clip: This one fit my Simpsons and Dialed In. Not sure about other SAM/JJP games
• Spike2 interlock clip: This fit all my modern Sterns (JP, Foo Fighters, Godzilla etc).
