Throttle Position Switch: Description and Operation
Fig. 14 Throttle valve switch
The throttle valve switch is attached to the throttle chamber, Fig. 14, and actuates in response to accelerator pedal movement. This switch has two sets
of contact points. One set monitors the idle position and the other set monitors full throttle position.
The idle contacts close when the throttle valve is positioned at idle and open when at any other throttle position.
The full throttle contacts close only when the throttle valve is positioned at full throttle or more than 34 to 40° opening of the throttle valve. The
contacts are open when the throttle valve is at any other position.
The idle switch compensates for enrichment during idle and after idle, and sends fuel cut signal. The full throttle switch compensates for enrichment in
full throttle.
