Biondo "Terminator" transbrake switch

[luckydog]

Anyone have any experience with the long Harrington button. How much is it worth?

[Aaron Allison]

I would say it is worth around 2 hundreth. I have never seen much more than that. I have also tried the Biondo 5-0 and I found that it was worth maybe .03-.035, but not very consistent. The best buttin I found to have a lot of delay was the AX. This button is no longer allowed in SS , but it could be adjusted to leave on the second bulb on the practice tree. It seemed like the more you had it adjusted though the more inconsistent it was. Temperature of the button also affected it a lot.

In reply to this thread:

Here is the breakdown on the Terminator Button. The terminator button has been tested to have a total of .040 to .045 worth of 'delay'. The button itself has .01 delay built because of the micro-switch placement inside of it. The remaining .030-.035 worth of delay is in the travel. As far as the shims, each button comes with a row of shims as well as a 'tip' sheet which tells you the value of each shim.

The Harrington switch has been tested to have .020 to .030 worth of delay depending on the user and how hard they press it down. As an average it has .025 worth of travel.

Location of the button has some effect also. We heard that some racers mounted the "Terminators" in a vertical position and got even higher numbers of delay. Vertically mounting the buttons caused the racer to hold it down harder.

As far as "inconsistencies" mentioned in this thread, the button MUST be hooked up to a practice tree in a pro tree mode to test for accurate consistencies and repeatability of any button. The Pro Tree is the best way to test a button since you simply react to the bulb, and not wait for the third amber.

Hope this info helps. We have very thoroughly tested this button.

thank you sal..your knowledge is always helpful.

I recieved and tested my terminator today and here are my results. I hit the tree 20 times at each setting and averaged my reactions, then zero'd everything to my pro tree switch.

Pro Tree Switch: .000
Terminator all shims in: .015
Terminator 2 shims out: .031
Terminator 4 shims out: .040
Terminator 6 shims out: .050
Terminator all shims out: .049

All the hits were made with the 1/8 inch shim in. So as you can see it seems to me the button is worth .015 over a quick releasing button and has approximately .035 worth of adjustment. As you could imagine with this type of button it is not as consistent as the pro tree button and the more shims removed the more inconsistent it became. Just thought I would let you all know my findings. Seems to me like if you really wanted to get some adjustment out of the switch you could mount another spring from under the terminator and attach it to the bottom of the spring inside the button. Just a thought.

Sal, Do you have have a button that will speed up us old people?

[John Lang]

Mr. Hill, in regard to speeding up buttons, you might try my way which has worked pretty well, and it's legal! I leave on the pre-stage lite! With my reflex's it comes out to be an .020. Some times a little worse. Usually between .020 & .080. Works for me. John Lang

Phil Mandella does with his button.

Multiple spring selections with delay numbers for each.

He also knows several "other tricks of trade" - there are lots of suspension/chassis things which can be done to bring the car to the driver in the suspension area.

Larry, I don't race but I have been told any of the following, or mixture of the following just before a run will speed up reaction times. 1. Using a jaw full of ground coffee beans like dip. 2. Taking a double dose of Pseudoephedrine. 3. 3 Jolt Colas. I can't speak for validity of cutting a good light but some mornings it sure beats the heck out of a mug of coffee.
