Romer-g's breaking easily

Has anyone else found it quite problematic to open up any of the Romer-g switches?
It's a bit of a hassle and I don't really know how to do it without completely destroying the bottom housing's clips.

You should desolder them first.

You desolder all of them from the PCB, remove them from any mounting plate, then it's trivial to open them up without smashing them to bits.
If you can't be bothered to do that you're going to have a bad time. And smashed switches.

I see, so even though they were designed with the intent of pulling the top housing without desoldering, they still break...
Thanks for the info!

I have no reason to believe these were designed to be delidded in place.

Umm... no. Very extremely no. I'm not sure where you got that information but it's not correct.

The blue one illustrates rather well why this is the case. The clips that hold the switch to the plate are part of the top housing. Above the clip that holds the switch on the plate is an indentation where the lower housing clips in. If you compress the clips to remove the switch from the plate, it just holds the lower housing tighter. If you spread the clips it grips the plate tighter.
In other words, there's no way to remove the housing in situ. You'll have to desolder.

Ah alright, noted!
