Lego Monorail Non-motorized Switch Rail Test

I considered a mechanism that would activate the switch rail when a monorail passes over it, similar to the switch rail on the original LEGO monorail.
It somehow works, but it's difficult to adjust and is not very reliable or durable.
At the moment I don't have any good ideas, but I'll think about it a bit more.
