I have an older Aristo wide switch and over the Winter it developed a sticking problem where the points wouldn’t go all the way to one of the edges. I removed it tonight to have a look and couldn’t find anything stuck in it. On the underside I found 2 tiny screws with springs on them. I ended up tightening them too much so backed off a hair and it seemed to have worked. The points now snap and hold on both sides.
Question is did I do the right thing?
