    Yes, connect them the same way. Mark them before disconnecting

    If it is not obvious, post a picture

    If the silver is a metal plate then it MUST be earthed correctly with the earth wires being connected to the earth terminal on the switch

    Just connect them the same.
    The two in Com, the one in L1.
    If it should work upside down put the one in L2 instead.

    As said you must connect the Earth Green and Yellow to the Earth terminal on the switch.
    For extra safe put another piece of earth wire from the terminal on switch to the terminal on the back box but this is not essential.
