Flipper Lane-change Switch, Bally

Bally/Williams pinball Lane Change switch.  This mounts on a bottom flipper End of Stroke switch stack along with the normal E.O.S. switch.  It changes the position of lighted lanes on the top of the playfield.  This allows getting all lanes off/on to get bonus points.  These are original Bally/Williams parts.
