Any Ideas Whats Happened To This Switch?

[Joooooosh91]

Hi All,

This morning we had a power failure of our shower. When I took the switch off the wall to check for any issues I noticed a section on the load side had "blown" for want of a better word.

I'm assuming its something to do with overheating but not sure - any advice?

Thanks,
Josh

Failure of switch. Simple.
What brand of switch is that?

Replacement required.

Well the wire terminations were fine, looks like the internal switch contacts overheated going by the bulge in the centre of the plastic.

Assuming your shower is 11kW or less if it's under warranty return it for replacement otherwise just buy a new switch. If your shower is more than 11kW then you need a higher rated switch.
