When I still had TA I used a Hurst T handle with Button, real simple and worked good.

Just use a toggle switch, mount it near your pointer finger on the throttle handle. Shifting up is up, shifting down is down. Very simple, cheap and reliable.

Normally Open Momentary switch. TA always on low side unless you hold button in for high side. No mistakes going down the track. Unfortunately I can't build you one right now as I built all mine out of aluminum stock on the lathe. Set 5-6 tractors up with them in last few years. Hold button in from 100-250 ft and let off shifts down no guessing game. I've seen too many toggle switches and foot shift switches either malfunction or driver error not paying attention.

Couple reasons why the momentary switch could cause issue. First off most guys are running 8 disk ta's now which freewheel in the low side so driving in the pits/unloading is much safer on the high side of the TA as it drives and functions like a normal tractor would. Secondly if something happens going down the track causing the driver to bump a toggle switch, chances are that same incident would cause them to slip off the button as well. Nevertheless any electronic shifting is a huge improvement over reaching halfway up the hood and throwing the lever. (Look mom no hands!) lol
safety should always be at the forefront this stuff as it only takes one mistake to end a lot of pulls on the local level.

I've been using a foot-operated dimmer switch between the clutch and brake pedals for several years now and have gotten along really well with it. I just walked into Napa and said "give me a floor dimmer switch from an old pick-up truck" and that's what I used.

If I were to ever do it over again, I might try a momentary push-button switch in my throttle handle, but use a non-latching dimmer relay in the circuit to get the same push-on/push-off functionality that I have now with my foot dimmer switch.

just run a rocker switch. Dairy Blend is right... most big TA's freewheel in the low side. much safer to cruze the pits in the high side..if a guy had an inexperienced driver it could get away from him fast going down hill. we made our throttle handle square and just mounted the switch on top. NEVER had any trouble

Is the stock lever design not as efficient as a toggle/electornic setup? Is it just a faster torque on the fly?

All Rules I've looked at say one hand on steering wheel at all times, except Stock class.

I used a throttle from mask machine, ended up using a toggle switch off eBay instead of just a push button to hold it the whole time. Works great

Use a latching relay with push button,push once for on and once for off.
