a very good solution

Delivered a total of six programmable switch socket and two independent switching devices (including associated batteries).

The manual is very good.

For programming via pins in the switching devices and the plug modules.

4, it is possible to program separate switching devices (1,2,3,4) and each socket switch 5 (A to E), or 20 separate switch. The system has no equal. Since all variants are possible - eg two relays and 10 switch or as otherwise desired..

Recommended: first to label the switch - then program to the pins. The switches have a sliding opening, the cans have a screwed Codierfach
Caution: Setting up the cans to pin-orientation - do not confuse the top and bottom

Conclusion: recommendable.
