Whats wrong in this pic of my clutch pedal?

[Razorhunter]

Early 04 5.9 w/NV5600 6spd.
New clutch and master/slave were put in by a big truck repair facility just prior to me buying the truck.
Everything works fine, but every time I push clutch pedal in, there is a loud clicking noise. Not sure of the source. It just sounds like its coming from the cylinder down there or possibly the safety switch. Anyhow, when I looked up under dash, this is what I found. I'm assuming this electrical component is the safety switch that tells the truck that the pedal is pushed in for starting engine. However, look close. You see the zip tie job they did and also to the far right you'll see that long white nylon strip/clip looking piece on side of switch is slightly broken/jagged/irregular shaped on the end (Towards the firewall)
This switch just basically freely slides on the shaft of the master cylinder. How should it be attached to the master? Can't tell whats missing but I know something is missing here. Prob some type of clip on the master cylinder?

In this pic you can basically see how the round white disc-like spacer/washer is loose and I'm not 100% sure how this safety switch is even activated. I pressed on both ends and dont really feel anything activating, nor do I see a button of any type that can be depressed.
So basically I'm wondering if that round white nylon disc needs to be RTV'd or glued in? Wondering of it pops out could any of this affect clutch function? Dont think so but figured I'd ask.

Clutch switch for sure. Easy to break on an older truck. Cheap to replace if I remember correctly.

I tried to post, your retainer is not correctly locked in position. And foam ring is missing.

Remove retainer make sure switch is correctly locked on to rod. It should feel spring loaded. Replace retainer slide it on switch. It locks on and wing tabs hold it in.

The foam buffer ring can be replaced w/o issue. Do not try to remove push rod.

Pm me if you need foam ring.

BTW, if you look closely in my pic, I think my retainer is broken. Prob have to buy a whole new safety switch, no?
