Hi,
In denmark the button is just a plastic cover to the real contact behind.
You can transform a switch into a push button by adding a small spring between the switch and the plastic cover.
I have transformed my both my switch 2 ways, into a 1 way by adding a spring on the back of the plastic cover.
Then you connect the line to each swith and connect all the switch wire to the SW1.
done
and you can have as many switch as you want.
