Amp rating of switches.

Understood, Neale! Thanks for your explanations. No danger of me trying out DC switches in an AC application - firmly in agreement that you use the equipment that's been designed for the job. Heh, lack of knowledge puts me in the category of a child that asks 'but why...?' Repeatedly!

You may well find that if you were to go to Halfords and look at the ratings on the switches, they may have an AC rating written on them. It's just they won't list it against the details of the switch, as they're only wanting them used in vehicles.

Switch ratings depend on AC/DC, voltage, and load type.
Personally, I wouldn't bother with that toggle switch, but if I did, I'd want it mounted to a metal control panel that is properly grounded.

I'd much rather use a rocker switch (round ones are available for those who don't like making square holes!), and preferably an illuminated one as it lets you know when things are switched on, and have power.

Yeah, I was looking at it again - it's a bit of a feeble thing - it had the shortest contacts which was what I was after. Just bought a couple of 10A 240VAC rockers from RS - half the price, double the quality - I have a feeling that the contacts will be a bit too long (the case is very shallow) but I'll give it a go.
