In replacing the above, the old switch serving 2 living room lights is wired as:
left side- 1x red wire at terminal 1 linked to terminal 1 on right side (live)
left side- 1x red wire at terminal 2.
right side- 1x black wire with red sleeve at terminal 2 (switched live)
back box earthed.
All working fine.
New switch has terminals L1,L2,C on both sides but when connected as old switch nothing is working with no switched live, what is wrong.
