Set Switch Circuit
When the "SET" switch is switched on (at the vehicle speed desired to be maintained, and the "MAIN" switch of the auto-cruise control switch on), the vehicle speed is maintained as a constant speed. Furthermore, the constant speed is gradually reduced (the "coasting" feature) when the "SET" switch is pressed and held while the vehicle is traveling at the previously set constant speed, when the "SET" switch is released, the vehicle maintains that newly set constant speed (the speed at which the "SET" switch was released). Current flows to the control unit, the auto-cruise control switch "SET", the junction block and to ground. See Fig 1 .
