Is there any writing on the board near these items?

I just save this in my Favorite Links

I did it! I found out how to stop him! I just locked the post and Abracadabra. Like Magic!

Oh an igniter.

Here is one such circuit.

How fast do you want these pulses to go?
How much Current do you want it to handle?
There are several names for it .
Multivibrator, Flip-Flop, Timer, Astable, Pulse Generator, Inverter, etc. -
Thanks for comming to my rescue. You guys are great. I tried a different tactic and it did not work either.
I first Complimented him on his helpful posts. Then asked him to open this subject for more study on the theory section and he thanked me for the compliment and threw out another argument.
Can't win against a know-it-all. ??? -
Here is a Fine example of your subject. I am getting a little Pissed over this one!

This may help decypher the code.

Would it be possible to use this IC to drive large Transistors like a 2N3055 so the circuit can handle Large loads?

can someone tell me what part this is ? I need to purchase more of these or an equivalent part. This part is probably about 20 years old so I'm not sure if its even available anymore. It came from a circuit board in an instrument cluster out of a BMW car. I assume the 100ns means 100 nanoseconds ?
What Year and Model is the BMW?
1986?

Yes that is a self reseting circuit breaker of a sort.

I did find this.

I had something like this on a crossover for tweeter protection. It was a circuit breaker that would open if too much power was sent to the tweeter. It reset it's self when you lowered the volume. My guess is a fast acting micro fuse and the time stamp tells how fast it acts. Just a guess.

I agree there is too much of this going on. I post a simple timer that has been tested and proved to work and someone comes along and picks the little circuit (that works great) apart. Analizing and critisizing and changing the original simple circuit into a Metro Golden Mayer Production.

You probably need to know about Lighting and Audio Equipment in a Theater Atmosphere.

A Speaker don't care aslong as it gets audio it makes a sound.

Could it be an SCR?
