Need some help with a 68 ignition switch key buzzer.
Are any of you guys familiar with how the little plunger on the end of the key tumbler pushes on the little brass contact at the bottom of the switch ? If so I have a question for you. Thanks

Pushing out but when you insert the key it pushes the plunge out even further. If I can find my little measuring tape I can tell you how much farther the key pushes it out, if you want to know.
With key in.
Key removed.

If you push in with your finger with no key does it try to spring back out ?
If you get hold of it and pull it out does it try to spring back in ?
I think the spring is installed wrong on mine.

Thanks thats what I needed to know. Your 2nd pic helped to.
The new cylinders like the one in my pic have a very heavy spring pushing the plunger out, which presses the little contact at the bottom of the switch setting off the buzzer. The key shop I talked to today said there's is also fully extended and under heavy spring pressue,,, so there not going to work. You should be able to remove the key and turn the buzzer off but this cylinder just makes it buzz.
( In my pic the key is not in all the way and the plunger is fully extended. )
I have a call in to Corvette Central about there cylinders,in their pic it is extended the same as yours.
Note -the cylinders at the key shop are $9 "extra extra extra" cheep but they wont work.
Thanks again

Glad I could finally help you seeing as you seem to have most of the answers for us.
It's probably a case of overseas help and plain not knowing what the thing was designed to do.
Hopefully it's just a faulty switch and Corvette Central can check their replacement before shipping it out to you.
Good luck Roger.

In this case the switch is good , its the tumbler assembly causing the problem.
Thanks for the interest , these 68s are rare birds.

Corvette tax at it's best!
Does anybody repo the switch with the place for the light bulb anymore?
I know Ecklers used to but they have this note now.
NOTE: Light socket is no longer made on the swtich. The factory wiring harness will attach to terminals but the three snap ears will not line up with the slots.
Copied and pasted btw. lol

OK I got this 68 back on the road with a working key buzzer (personally I hate the buzzer).
There is no way the key tumbler/plunger assembly that I looked at would do anything except make the buzzer buzz with or without the key in.
I had to remove the plunger , discard 1 of the springs and grind 1 part of the plunger to a smaller diameter.
I know this is not a popular subject so I won't get too involved in describing it.
If anyone is having a problem with this let me know and I can go into more detail.
