Dixie II+ VCO/LFO switch faulty

I bought a second hand Dixie II+ which has an issue with the switch between VCO and LFO mode. It takes a lot of switching back and forth before it responds and changes mode. I guess some kind of contact issue? Is there any way to fix this?

I imagine the switch will have to be replaced, but it might be possible to fix the issue with some electronics lubricant.
