An actuating structure is provided for a lock having a barrel with a plug which is key-actuated for rotation therein, and a switch having a shaft and rotor rotatable with the plug. A first lug is fixed relative to the barrel and a second lug rotates with the plug. A first stop washer is provided having two slots therein, one slot receiving the first lug to allow limited rotation of the first washer relative to the barrel and the other slot receiving the second lug to allow limited rotation of the first washer relative to the plug. A second stop washer is also provided having two slots therein, one of the slots receiving the first lug to allow limited rotation of the second washer relative to the barrel and the other slot receiving the second lug to allow limited rotation of the second washer relative to the plug. A spring is provided to rotationally bias the stop washers in opposite directions.
