Help to identify a volume knob

[gutabo34fr]

Hello everybody,

I would like to repair my car stereo who has a faulty volume knob (it is also the power button).

I opened the thing and found that:









It is written "0552" and something like "HDK". Tried to google the stuff but I didn't find anything useful.
Can you help me identify this part? Where can I buy a spare?

Thank you!

hi there
welcome to EP

going to the manufacturer of the car stereo would be your best bet.
Its quite possible that the part is custom designed for them

These are encoders with tactile switches. This is probably the brand and basic model used but all parameters must be specified to order as they were by the manufacturer of your car stereo. As Dave said, the stereo manufacturer is your easiest source if they'll support component level repair. Panasonic is quite good at this but others?

Thank you guys.
So it is an encoder. That's a start.
Unfortunately, it's a factory stereo from Daimler Chrysler. I doubt they have such a support.
Maybe I can give a try with this:

Thanks again.

quite possibly
but could still be a standard vol control. does it rotate continuously with soft clicks ?
ie. doesn't have a limited range of movement ?
if so, then pretty much guarantees its a rotary encoder

Nice find. If it's a dimensional fit, it'll probably work unless the problem lies somewhere else.

It does rotate continuously w/ soft clicks. It also has a push switch that come comes back when the pressure is released.

Yeah, that's pretty cheap, it worth the try. And I like doing this kind of stuff
