These early solid state pinball buttons are made in "modder friendly" colors and are based upon the original C904 opaque buttons made for many Bally, Gottlieb, Stern, and Chicago Coin Pinball machines in the late 70s and Early 80s.
They were typically given the following part numbers:
- Bally C-905 button
- Gottlieb B-16680 button
- Stern / Chicago Coin Machine 4B-200 button
These are not exact duplicates of the original parts - as they have been modified to make them injection moldable and make slight improvements to allow for additional modding. Specifically:
- the Critical parameters are the same - such as button / housing mating surfaces so they can be interchanged with existing housing or buttons.
- Wall thickness has been grown to ensure a quality injection.
- Button Face has been thickened to 3mm for deep laser etches.
- Button Switch pole has been changed from a cylinder to a cross. (See pictures below)
- These button came in two sizes which are generally interchangeable. Gottlieb used created a button with a longer pole (by about 1/8"). While Bally used a slightly shorter pole. To ensure compatibility with all games; our product has the slightly longer pole. Some experts recommend shimming the switch assembly; while I've just been using them as a drop in; adjusting the switch stack.
The Translucent Buttons are made out of PMMA (Acrylic) so they can be laser etched on a CO2 laser machine like I did on my Original Bally Star Trek Restoration. The Opaque Blue buttons are made out of ABS and cannot be laser etched.
Colors are show below and should represent the colors. Keep in mind your monitor and my camera's color balance will throw the colors off a bit from the actual product you receive so use these as an approximation of what will be shipped to you.

This button is a bolt-on replacement for your existing button and should be obvious how to install. Simply remove the existing button via the two screws and the flipper switch and reinstall your new button.
