How Fliptronics flippers work
From The Addams Family (1991) on, a Fliptronics board in the upper left of the backbox, above the CPU board, runs the flippers. Pressing a button sends 70 V to the power winding; when the low-voltage EOS switch closes, the board switches to the hold winding. If no EOS closure arrives within a short time it switches anyway, so a broken or misadjusted EOS switch does not burn the coil. The CPU can also flip on its own, and unused flipper drivers on two-flipper games such as Theatre of Magic or Tales of the Arabian Nights run other coils.
