Super solution at a fair price!

The switch makes a "click" sound when switching, so you get even with acoustically that the unit switches (such as a relay just happens to "clicks").

* Important to mention: *
The machine is set with the coding wheels on the rear side. There you can screw in the channel, for example, C 8 or M 4, etc. At the transmitter must then be screwed in accordance with the same code. What in turn means that you can only use those channels that operate via the encoder wheels. Thus, unfortunately, is the double switch (see wireless wall transmitter / switch InterTechno ITW-852) is not possible! One should make sure to first check and consider whether to do with a switch.

A negative point for me is the size of the component. It is a bit difficult to accommodate these in all light hangers, so this is no longer visible. Stupid, especially in ceiling lights that you should also consider absolutely no space for the installation of the recipient haben.Hier whether the switch may be different "hiding", if you want (for example, false ceiling, etc.) or to fixed him up next to the wall.

I am fully satisfied with the solution - especially since a prying and new lines / switch massively embarrassed a lot of work and effort (especially in a residential home) would have meant!

In my apartment the transmitter / receiver at a distance of about 5m crow - works perfectly!

One point deduction, there by my side for the size and for encoding via encoder wheel that make it so only compatible with a transmitter.
