Light control: Switch with bistable relay for two circuits

Hey,

I currently have a 5-bulb lamp in my room which is switched on with a normal double switch (there are two circuits).

I would like to replace this switch with 1 switch with a bistable relay(s) that:
if the user holds the switch for less than 2 seconds - will switch on one circuit, if longer, two circuits.

Is there anything ready on the market that I am looking for?

Ultimately I want to get myself a siemens logo and I think such a controller would help me a lot, but at the moment I would like some simpler solution.


kind regards
s

And how much space do we have?

no limitation

And switching off how?

You could use a bistable candlestick relay, e.g. http://fif.com.pl/produkt/26/263
has quite useful functions (almost like the premise of the thread)....
