Hello, does somebody know where i can buy a hazard switch?

Rare stuff! Perhaps yours can still be overhauled:

Is this a common failure on all E21's or the later cars are more affected by this? I noticed that most of the pictures on this threads refer to the hazard switch on cars underneath the central speaker, on my 78 E21 this switch is close to the steering wheel.

Correct, this is mainly an issue on the facelift E21's
