Blue Star Trek "Engage" start button.
Perfect for Williams Star Trek The Next Generation and Stern Star Trek pinball machines!
This start button will replace all Stern start buttons, some Sega start buttons,  some Data East start buttons, and all Williams/Bally WPC and WPC-95 start buttons.  Basically, if the start button is a 1" diameter lit button then this button will replace it.
Blue button lit with a blue LED lamp.
