I just checked my NOS 54 switch with a meter to see how it works.
All the way counter clock wise is off, the key can be removed.
Center position is on or run. The key can be romoved. From the center position the switch can be turned off with a screw driver by turning it clock wise.
All the way clock wise is the off position for the "screw driver key" method. The key can be inserted and turned to the center position. This is the ranch hand option that others have mentioned.
