Replacing double light switch
I'm replacing a double light switch, near the front door. The left hand switch (right side when looking from the back, as per the photos) controls the outside light, the right hand switch controls the hall light, as do two other switches in the hall.
I've removed the white plate, which has a 1(1way), 2 and COM port on each switch.
I've installed the grey plate, which has L11, L12 and COM on one side and L21, L22 and COM on the other side.
There was also a loop wire connecting the left sided "2" to the right sided "1(1way)". I've replicated this on the new switch by connecting L12 and L22.
Now I've switched it over the switch controlling the outside light works but the switch controlling the hall light does nothing. It doesn't trip the box. The other switches controlling the hall light also no longer do anything.
