I removed an old light-switch and the following appeared: enter image description here

I went to Brico, showed them the old switch, and got the one below.

I am wondering a bit how to connect it. I am a bit worried that I only see 2 metal screws. (2 lower right ones)

(It is quite certainly not 3-phase, but perhaps ground)

(Probably basic, but is there some way I can measure if something is ground or not)

    I would think that the green wires are grounds and that the yellow and red connect switch terminals. But it might have been helpful to take and also to include a picture of the old switch before you unwired it. – Dan D. Mar 1 '14 at 11:17
  • Tested with a bulb. CUrrent between Green and red, but not between greens and between red and yellow. – Olav Mar 1 '14 at 14:33
  • Somebody explained it was a dual switch setup. – Olav Mar 1 '14 at 18:56
  • It would be helpful to know where you are located. – Brad Gilbert Mar 2 '14 at 17:16

    if it was a dual switch setup then you got the wrong switch, you need a 3-way switch for that – ratchet freak Mar 3 '14 at 13:33
