Currently have an old dimmer switch but have now replaced light fitting and want to revert to a simple on/off switch. There is only one switch in the room.
The photos below show the current wiring configuration. I think I should have bought a one gang one switch type but inadvertently seem to have purchased something different. Can I use the new switch (2nd photo) and if so should I wire the three lives in different places i.e. L1 - L3 or should the two live wires at the top remain together? Thanks
