4QD’s Bell throttle assembly is a finger-tip operated ‘position sensor’ which is also very suitable for use as a position sensor for a foot pedal operated throttle.
The diagram shows how it might be done.
There is sliding between the bolt head and the throttle lever – but this is steel against vinyl and proves to be very reliable even in the dusty, dirty and wet conditions encountered on a golf course. The vinyl lever cap is, in any event, very easy to replace.
We have at least one customer who has been using this system on a golf buggy for many years without trouble.
The foot pedal will need its own return spring (the Bell Throttle has a light spring) and suitable travel stops.
