Problem...too much electricity!

The existing switch is a 1 gang 1 way switch however the new switch is a 2 gang 2 way which if I correct of your post is a incorrect switch. Unless and forgive me if I've mist something posted here but you are changing this switch is this the cause of the light not working ?

Thank you Anthony,

You're quite right and the erroneous bit is my doing. I bought two 2-gang switches, not realising the upstairs one is 1-gang.

I'm changing the switch because the stair head light stopped working. It wasn't the bulb and an LRD probe showed both lampholder pins had current, as did the earth.
A neon now shows that on pin in the lampholder has power but there's still no light (I tried two bulbs).

I believe most MK accessories come with the screws undone ready to just be tightened up.

They are manufactured in a manner so the screws don't shake out during transport, but this has the effect that quite substantial force can be required to tighten them past their original as shipped positions. So you may need to give them (technical term coming up) a bit of welly!

Good advice, Sparkychick! I found a really well fitting screwdriver and ran the screws fully in and out with it. It took quie a bit of thrutch (Derbyshire word) to achieve this.
It would appear there's some sort of threadlock compound on the threads.

It all appears that it may be rocket science after all!

I am familiar with the term thrutch although I wasn't aware that it's from Derbyshire (I'm from Leicestershire originally). I was introduced to the word listening to Blaster Bates

And glad I could assist.

Blaster is a legend. I wish they'd re-release all his LPs, not strictly PC but a bloody good laugh
