Rollover Buttons

A type of Rollovers consisting of a small, round button — usually plastic — set into the playfield surface that registers a score when the ball rolls over it. Rollover buttons sit slightly proud of the playfield, depressing under the ball’s weight to close a switch beneath. They serve as simple scoring triggers or sequence targets, often placed in lanes or scattered across the playfield in patterns. Rollover buttons were common on pre-Flippers and early flipper-era machines of the 1930s through 1950s, predating the flush-mounted Star Rollovers that eventually replaced them in most designs.
