No exaggeration, this is one of the worst designs I’ve ever seen. Sufficient testing before the item was released would have identified this issue.
These connection posts are incredibly fragile. A post became disconnected on two different switches within 15 minutes. The issue is compound because there is no easy way to try to fix them. They can’t be accessed due to being inside a plastic casing. Tiny Torx screws were used instead of Phillips heads presumably to keep people from removing it.
I see other people have complained about this as well.
