I have already bought a lot of Kopp-way switch. From the beginning was impressed by the stability. Here you can screw everything firmly, and it sits at the end everything was great. The rocker itself is so ne thing. There are more streamlined, but there are still far folding complicated switches. He is here about the middle. For me it is tight enough. The cable connectors inside are super. Man presses a button, pushing the cable into the inlet, the button lets go again, and the cable is firmly seated! One must not screw. Also inside the switch enough space to every 2-3 Cable (depending on whether it is used as normal light switches or changeover switches) to move easily to the inlets. Up to this point the part is great. Only one thing bothers me always enormously, and for that there are also a star deduction. The plastic is extremely brittle. If you try one of the pre-marked points rauszubrechen, so you have a gap for the fitting of special cable, you can break away more than you really want. You have to be very careful. But no matter how careful you are going, there we never broken off cleanly and perfectly round. That's why I have got used to the cable inlet always be affixed on the bottom so that it does not interfere in everyday life visually.
