wide open throttle switch problem

Hey guys,
Did some searching, found This thread and followed the steps detailed there. Turns out my wide open throttle switch is broken, and I have scoured the internet high and low trying to see if I can't find a new one, no luck so far...

Says here though that its just a normally open switch which closes the contacts when the throttle is all the way open, I feel like I could just buy a button at radioshack and mount it so that it does the same thing. Does anybody know if there might be any problems with that plan?

Any updates? Did this work? My WOT switch needs replacing and I'm in the same boat.

Anyone else know where to find one? The link above no longer stocks it. Much appreciated.

Yeah, I couldn't get it from the supplier either. I think I'm going to radio shack and pick up a simple SPDT level switch. In my case, the switch mechanically closes and won't mechanically re-open (like an electronic latch). Therefore, the engine always assumes a WOT condition and my engine runs rich (of course I have other failed sensors that are causing it to run rich too). I'm curious what the affects on performance would be if I just disconnected the WOT switch. Since its a normally open switch, an open connection wouldn't matter. Of course, if I needed to put the pedal down (going up a hill, or hitting a headwind), I wouldn't have that extra response from the injectors. Anyone got any thoughts?

I have looked and I can find a production source. I can't believe that it isn't sourced anywhere. A cherry switch should work but it will have to be mounted correctly. I am looking now too. Maybe we should try posting on the older XJ forum as well. They used the switch as well as the wagoneer.

I got lucky. After giving up trying to find one, I freed mine up via squirting a shot of wd-40 at the pivot point and working it back and forth for a few minutes. Now it doesn't stay stuck in WOT anymore.
