Brake pressure switch

[Mile High]

I've been using the one that came stock on my 64 Falcon. Screws into one of the ports on my linelock now that I'm using a non stock master cylinder. It's nonadjustable so I adjust reaction times with tire pressures.

I haven't checked yet, but I've been told that a Volkswagen brake light switch (not sure what year) will work.

Notch1320, thank you for the info. I tried contacing the man you suggest but he said that I have to order the 10 min. So that will not work.

Phillip, where did you buy your GEMS switch from? I left a messsage with GEMS with no return yet. Any suggestions would be appreciated.

I have thought about the stock brake pressure switch but the ones I have found have a very low pressure on them? I might be wrong.

Thanks, please keep the ideas coming.

I ordered it from the website.

They have a bunch of options but the one I ordered did what I wanted it to do and they pressure setting is adjustable unlike the old ford and VW switch's.

Phillip, I tried to order online at GEMS, but it would only allow me to order 10 at minimum. I will try again, that is why I tried to call them. Thank you for the info I will look up the switch you use.

I ordered four when I bought mine. Even if you had to buy 10 you could probably sell the extrs here,lol

I use a switch from PDI PDAH-4-4M-C-FL-9. There are older versions of this switch that have a similar part number. There are a couple of these currently on ebay.

You need a second switch in series on the shifter in first gear position so that the brake pressure will closed the micro switch when you step on the brake at the starting line and the switch on the shifter most be in first gear and closed also for the two step to be activated. This prevents the two step from activating at the finish line if you foot brake at the stripe. I use a common bump switch for the shifter mounted on a small bracket. I brake pressure gauge with a small light built into it is also a good option also. The pressure switch must be installed with the red wire (Normally open) and also the black wire = common. The pressure switch is adjustable, remove the screw from the top of the switch, using an 1/8 allen wrench to adjust clockwise to increase set point and counter-clockwise to decrease set point. Then replace the screw. Works by staging, stepping on the brake hard, stepping on the gas, releasing the brake to launch.
