How a pinball button becomes a flipper swing
Pressing a flipper button closes an electrical switch. Current then flows through a tightly wound copper coil, creating a magnetic field. That field pulls a movable iron core—called a plunger—into the coil. A metal linkage transfers the plunger’s short, forceful movement to the flipper bat, pivoting it upward.
The mechanism turns a brief electrical signal into a fast mechanical strike. The player is not powering the flipper directly; the button tells the machine to release energy supplied by its electrical system.
Why the action is so quick—and why it must reset
A flipper has to move fast enough to meet a ball that may arrive only moments after leaving a bumper or ramp. The coil-and-plunger arrangement produces a sharp pull, while the linkage converts that pull into rotation around the flipper’s pivot. When the button is released, the magnetic force ends and a spring returns the bat to its resting position.
That cycle also creates an engineering constraint: a coil carrying current generates heat. Pinball mechanisms therefore use electrical controls to limit how long the strongest current flows, rather than treating the coil like a motor that can run continuously. The result is a powerful burst when the player needs it, followed by a reset ready for the next shot.
A small machine doing precise work
The flipper’s familiar snap depends on several parts acting in sequence: switch, magnetic field, plunger, linkage, and spring. If any part is slow or poorly adjusted, the bat may respond late or fail to return cleanly. The player feels one simple button press; inside the cabinet, it triggers a timed chain of electrical and mechanical events.
