Light switch On Metal Cabinet

[Tigercubrider]

Just to muddy the water you could fit a 12v relay to switch the 240.
I think it needs a special relay to ensure that no mains gets to the 12v?

we use a contactor in a workshop where the key switch powers up the mains and acts as a panic button to kill the supply

Where does he get the 12v from?

Potentially a transformer. (Even a battery)
Keeping the stated worry of mains voltage away from the metal cabinet.

However there can be (afaik) an issue with a standard relay being able to feedback 240 onto the 12v side

Another alternative could be

I have used them to control shop fitting lights intended to light a lecture Dias once a week.
The advantage over a relay is that they switch on/off via remote but don’t rely on voltage to stay on.

Well today a solution was sorted, last night I ordered a 2 gang wireless light switch kit from amazon which promptly arrived this morning.

Wireless receiver wouldn't fit nicely inside the dry lining box so I mounted it on top.

Light and box fitted,

Wiring tucked neatly into box,

Cover on/ finished installation,

And the doorway which presented the issue, with the new wireless switch nicely mounted.

Overall I'm happy with the solution and thanks to everyone for their suggestions, I didn't know such a thing existed before this thread, now just another 9 lights to wire up but they'll probably wait until after the ceiling is plastered.

Thanks for the feedback but I'd love to know what advantages you have over the cheaper option in this crude sketch.

That's a deception of the photo, with the cabinet squared up in its final position there's not even 5mm of brickwork there to mount a conduit.
