Here in the USA we have been bypassing that switch for at least ten years now. There are no new parts available and most used parts from "junk cars" are also defective.

There was an individual that was "3D printing" an alternative plastic assembly that I think used a replacement switch, but that was some time ago.

Bypassing the divider switch means you must be sure the divider is up or the area in the trunk is clear before lowing the top, I would not bypass ANY other switch, just that one.
