Thanks for the fast reply.
There is actually a socket right next to the switch (it's a switch/socket combination). But even then I can not make it with the current wiring, can I?

Because I would need:
a. a circuit that provides power to the Action-swich (probably the bottom (black) wire and the top (blue) wire in my picture)
b. a powerless circuit that runs to the lamp and back (and connect that to the middle (black) wire and the top (blue) wire in my picture)
(Note: there is probably no easy way to run new wires; would official Kaku material be the only way then?)

Sorry for not responding sooner. Due to personal circumstances I'll have to postpone this a while. Apparently I forgot to post a link to the picture. Here it is for future reference for anybody wanting to modify the Action switch:

Can somebody tell me how to connect the wires from a light switch to this kaku board? And why is there 2x a red wire? I am not sure how to solder the wires (Dutch wiring)? This is really a great way to use kaku behind a light switch!
