Stop Light Switch Circuit
When the brake pedal is depressed during constant speed travel, the stop light switch's (NC) contacts for the auto-cruise control system open, with the result that the current to the electromagnetic clutch of the actuator is interrupted, thus, cancelling the constant speed travel. At the same time, moreover, the closing of the (NO) contacts for the stop light results in the sending of the cancel signal to the control unit, so that the actuator's electromagnetic clutch current is discontinued within the control unit, thereby canceling the constant speed travel. The flow of current is from the battery to fuse No. (12) of the junction block, the stop light switch, and the control unit.
