Fairly quick one... I'm replacing our fan isolator switch in the bathroom. I am using a proper fan isolator switch from Screwfix. The switch which was there has given up. Inside the box there are 2 earth wires which were twisted together and connected to an earth connector on the facia of the switch - not in the switch "connector block if that makes sense... What do I do with them in the new switch? There dont seem to be any dedicated earth connectors on the switch unit, they're all marked as L or N. I have it wired with the fan working fine when the light comes on. Do I leave just earths connected together and just tuck inside the box? Thanks!
