Garage light switch

[scott_369]

I realise this is probably a stupid question but anyway...... 

I have a question regards my garage light switch 

Its a single switch which was replaced when i had some work done not that long ago anyway the switch has been playing up so im going to replace it, when i opened it inside there are the following 

2 brown live wires connected 

Then the yellow/green earth is just capped off and not connected 

And 2 blue neutral also capped off and not connected 

Is this normal? My knowledge i quite basic but i thought the other wires would need to be connected as well. If anyone can explain it would be appreciated 

Thanks in advance

Sounds standard

brown from mains in one terminal

brown to light in the other

blue from mains connected to blue to light

2 Earth wires connected together

makemsure to,turn leccy off before you fiddle with it

If it's a metal switch box or metal switch plate, the earth wires should be connected to those.

I assume by "capped off and not connected" you mean the two blue wires join to each other in a connector block?

Sorry just realised what i wrote there

Yes the two blue wires join in a connector block from each end. 

Its plastic switch plate and box

Assume the earth would only need connecting if it was metal?

The earch is in a cap end protector box

sounds like normal wiring...

Cheers had a few questionable electric wiring in the past so just wanted to double check why the earth wasnt connected but yea forgot that its a plastic box so doesn't need it. 

Also thought that the blue would need to be connected to the switch plate but guess not. Told you it was a stupid question! 

Thanks
