Switches type number GZUA4125SQ

Hi guys,

Can anyone help me what type number both switches are? They are extremely rusted. They need a change unfortunately.
Looks like one is a single channel switch, the other is a dual channel switch.

Thanks!!

Amp make/model?

If the appearance isn't an issue, you may be able to disassemble them and get them working. The steel casing gets corroded but the contacts often just need a light cleaning. The casing will have to to be scraped until completely free of scale. I applied a grease to the switches. I used the DeOxIt L260CP but they now have a DeOxIt L260D which may be better.

Hopefully someone will have a source for new replacements.

They are so rusted that it's not possible to move the switches. Cleaning is not really an option.

Type number of the amp is a GZUA 4125SQ

I suppose its a pretty standard switch. But I never ordered any of these switches new. Mostly took them out of unrepairable amplifier, but in this case I would like to buy them new.
Doesn't need to be the exact same switch, as long as they will work I'm very happy

Measure the pin spacing and look up the datasheets for switches that look similar. Each one appears to be two position. One has 2 circuits and the other has 4, from what I can see.

Yep, thats correct. I measured from a good working switch as reference. The possible switches:
6 pin 2 position
12 pin 2 position
11 pin 3 position.
The distance between the pins is +- 2mm (maybe 2.1-2.2mm)

Really hard to find switches like this in my area. They all have a slightly different model.
