Stand on the switch, on the left an the platform on the ground will move over and push the crate over the switch on the right for you.
I'm glad you found it fun. Troll games aren't for everyone.

I think I beat that level - at least a level with that mechanic - so it might be a later level than that where I was stuck. In the level I was stuck in there was a crate at the top right after very long vertical stairs spanning the whole right of the level. (and spikes above the crate just to troll people jumping over it without pushing it)
