Switch Input

Various switches provide information to SMEC. These include the neutral safety switch, A/C clutch switch, speed control switch and brake light switch. If one or more of these switches is sensed as being in the "ON" position, SMEC will signal the AIS motor to regulate idle speed at a scheduled RPM.
