What internally turns off the hazard switch?

[NotaBronco]

I'm pretty sure it's the correct part. I crossed referenced the a/c delco switch with the Borg Warner part and had Orielly's Auto check to make sure it was correct as well. Turn signals do nothing to cancel the hazards as well as turning the steering wheel and pushing pressing pulling on the hazard knob. I figured the cam inside the column that also cancels the turn signals would do the same for the hazards but it doesn't. I've played with the new switch and the old and they both operate the same way.

Anothe clip of the switch installed.

I had that exact same issue when I replaced the turn signal switch in my 69 C20. All I did was install it and put a little force by pulling it out to turn it off. Now I can turn them off like normally.

Did you pul out on the switch assembly or the hazard knob?

Nope, I just put it all together and then after turning the flashers on I tried pulling the knob back out and after pulling with enough force it finally gave in. I'm pretty sure the part of the clip that locks it in is just a little too high because I got the same replacement switch so it just takes some force on the first unlock to make it able to be turned on and off with ease.

my '71 has a red button that you depress to turn on the flashers, and pull to shut them off.

My 72 Blazer had the red switch too. Does anyone know the specifics of switches (red skinny one vs black round one) as it relates to years/plants. I am sure there has to be some pattern.

The skinny Red Hazard Warning Switch was the original part. They get brittle and sometimes snap off. The Black switch with outer ring was the AC-Delco replacement. The red switch was earlier nd the black switch was later production, but I don't know the timeline for certain.
I thought the red switch was from '68, [my '67 has a chrome button like a door lock tab] and the black switch came on by '70 or '71, but I see red switch examples in later trucks, so I'm confused.
I remember replacing my red switch Turn Signal Switch assembly in 1978 when the red tab broke and there were other issues with the TSW. The Chevy dealer sold me a black tab T/S Switch as factory replacement.

The 67s came with either a chrome knob or the red one. 68-72 model years only had the red one which is what I have in my 69 now after finding out the original design switch is reproduced. If I'm correct hey changed it in 73 to 94 to what you get now at most if not all autoparts stores. Here's a photo of our 94 silverado and it has the black one. I personally don't like the black one. I know you can get an original design switch at classicparts.com
