We have here a pair of Wurlitzer jukebox Readout switches with mount screws

These would be mounted in the lower part of the mechanism above the selection pin bank.

They are on a flat bar that rotates looking for raised pins on the pinball. When one if these switches encounters a raised pin the mechanism emediatly stops rotation and proceeds to play the record in that position.

These were removed from a Wurlitzer model 3600 Superstar. I'm pretty sure they will work in models 3400 Statesman, 3500 Zodiac, 3600 Superstar,  3700 Americana , 3800 Americana, 3900 Americana.
