Flipper End of Stroke (EOS) switch, with slight bend.
This is a N/C “Low Current” EOS switch.
It was only used on 5 pins, (that I’m aware of) as follows
Data East: Royal Rumble, Guns N Roses
Sega: Maverick, Frankenstein, and Baywatch.
The EOS switch is used to tell the computer when the flipper has pulled in all the way, which in turn then controls the current/power to the flipper coils.
A broken EOS switch will cause weak, overheating, or malfunctioning flippers. For use on electronic (computer-controlled) flippers only.
Data East 180-5124-01, replaces 180-5124-00
