Replacing 6 Gang Light Switch -Crabtree to MK

[ian283]

The switch which is 'faulty'. Label which wire goes where, and disconnect them both from the switch. put them both into a piece of strip connector, and see if the MCB will stay on.

This will show for sure if the switch is at fault.

If you fit your new switch and the fault still exists, then you risk welding the contacts on your new switch.

Would it not have been easier to get a replacement crabtree module, rather than having to replace the entire grid switch?

Thanks for the tips and suggestions from all. I will try this at the weekend. I will also locate a crabtree 6 gang switch replacement as this will easier to wire like for like.

I have been unable to check the resistance yet as it invlolves two people to take the unit down hold it etc.

I may get a sprk in just to sort it.

Will let you know results.

Thanks again
