A numptie question I fear. I'm looking at buying a simple on off switch. The one I favour is described as being "adjustable" for 12V or 24V. (Chinese I imagine).

Does this just mean it is rated at up to 24V and will be fine with 12V? I mean, can you even have an adjustable voltage switch?
 
Does it have a built-in LED light?
 
At low voltages like that it won't make any odds what is more important is the switching current.

Rated at 20A which is the rating of the existing fuse for that circuit.

I have similar switches on 12 volt lights inu caravan and also on the car. The one in the car is to switch off the tailgate light when the tailgate is open for picnics etc.

Get a branded one like Arcoelectric.

Yeah, I've been checking those out. Nothing fits my spec so far. Other brands?

The switch will probably be rated at about 32V max. However it has a built-in LED. I'd guess the LED will take either 12V or 24V, but the 'adjustable' may refer to some kind of adjustment of the connection. I've never heard of that before though.

Cheers. It does sound a bit weird. Maybe a Chinese translation issue? :giggle:

The LED will work on either 12v or 24v. There will be no 'adjustment'. It's a translation issue as suggested by acropolis22.

Yep, it will just be a bit brighter on 24v.

Just a quick pointer - I've used the one in the Amazon link above for a few projects - but note that the terminals are not labelled - and the photos in the link indicating that the central pin is the negative is incorrect.
The actual correct wiring is -
The bronzed pin is negative
The centre silver pin is the switched positive
The other silver pin is the permenant positive

Work fine by the way.

Thanks, that's really helpful. I've been casting around trying to find out the correct connections. Guessing by permanent positive you mean the positive supply and switched positive is the load or device that I am trying to switch. As you can tell, I'm pretty amateur with electrics.....

That's exactly right, and using better terminology than I did! 👍
