What does this switch do? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey wondering if anyone knows what this switch is for or what it does, I have no clue, never seen it before. It's mounted to the gas pedal bracket and from what I can see it appears as though when you step on the gas pedal (accelerate) it hits this switch. I haven't looked at any diagrams yet but thought I would run this by everyone for some help. Here are the pics and this is a from a 1971 1 Ton Dually just in case that may have something to do with it. Thanks

I've got one on my truck too, How are they suppose to be adjusted?

Ah that makes sense now

I knew it was something pretty simple, thanks very much.

I think you can slide it on the bracket can't you, I'm not to sure I'll have to take a closer look. I never worked with a TH400 before so it's pretty knew to me.

other than fpr damage... why would you need to adjust it?
