A snap-action switch operated by movements of the accelerator pedal is interposed between a D.C. source and a downshift circuit actuator of the automatic power transmission in a manner that once the switch closes by nearly full depression of the accelerator pedal, the switch remains closed unitl the accelerator pedal is permitted to return to or beyond a partially depressed position corresponding to about 1/2 open position of the throttle valve. The saving of fuel is accomplished by the "lost motion" existant between the boss portion of the rod and the respective projection surfaces engaged by the boss portion in the acceleration and deceleration phases of operation. |
