BSA C15 Light switch screw

[Dave H_C15]

Does any body know what thread size the light switch screw is as i've lost mine and need to source a replacement.

Total guess... 2BA? BA is incredibly common in electrical fittings, especially old Lucas items too. Is this the 'usual' Lucas rotary light switch? The screw that retains the knob on top?

Hi Calum, Yes it's the usual standard light switch. I will try that.

I had a quick look at my spare switch and I am pretty sure that is what it will be. I can measure for you if you need to order a screw only to find it might not fit!

Hi Calum
               If you could measure it for me that would be helpful.

Thank you.

Hi Dave

Apologies for the delay. As best as I can measure and compare against a tap for the pitch, I can confirm it is indeed 2BA.

Cheers
