Thankyou. Do you know if the relay can be replaced on its own? Or it needs a new switch?

Thankyou. Will get it checked. It does seem odd that only 1 'half' of the switch has blown. Since the other load still works.

I am based in the UK. Would I still expect 120V? Or rather 240V?

I have a dimming light switch connected to 2 loads. It’s been working fine for 2+ years. On Friday, I had a smart meter installed. An hour or so later there was a pop from the direction of the light switch and all the lights went out. I reset the RCD and it didn’t trip again. The light switch lit up but now only 1 load is being controlled. Composer HE shows the light switch and both loads as being connected/active. I can set the light on/off and dim up/down but the light itself doesn’t come on. I’ve checked with bulbs from the working load but still nothing. I’ve tried resetting the light switch (15x top button) but nothing. Is anyone able to advise on what to do next? Is there a way to repair the switch? Or do I need a new one?
