Soundcraft K series switches

I had a few channels come in from Soundcraft mixers I am not 100% certain they

are from a K1 2 or 3 but one pcb was marked " K channel spare" so I have listed them

like this .

Price for one

I have two types they are smaller than the regular ones one has 12 positions probabyl 4pdt the other has 18 so i am guessing its 6pdt
