Something like that was the experience with this product. The automatic switch for the filter holder hangs when you press this, even without the support of the filter holder.
Once you installed the Siebträgerhalter, whether big or small, you can press the automatic switch only once, then remains of these hanging in the plastic version.
Here I would have expected more in terms of accuracy and quality control.
The holder for the switch is clearly too short and know clearly tensions on. By the 2nd holder the tension is even more evident, since they do not really fit well.
Let's see how it looks at the replacement unit.
