Loop-in at switch

If you require a screwdriver to access the connections that is deemed to be safe in it not?

You can't please everyone all the time.

A switch may be fairly simple but I don't think, in general, manufacturers design their products in such a way that those who haven't a clue can fiddle with them safely.

Take the back off a TV.

If you require a screwdriver to access the connections that is deemed safe according to BS7671 or as my lecturer put it you require a 'tool' to gain access :cool:

Probably true but, in this case, I think that the design we are talking about also makes it more likely that some of those who "do have a clue" will, as a result of 'human error', create a bang (hands up every electrician who has never put the wrong conductor in the wrong terminal!!).
I'm not sure that is necessarily a very good example/analogy. 25 or so years ago, I would have agreed with you - but I think that if you took the back off a more recent TV, you'd probably be very hard-pressed to find anything hazardous to touch. They might mess the TV up by fiddling, but I doubt that it would be 'unsafe'.

Apart from the 230v mains supply.

Safe in terms of protecting people from contact with live parts, yes - but the need for a tool to gain access does not mean that what goes on when the connections are accessed is necessarily 'safe'.

It's a long time since I last saw 'touchable' 230v mains voltage in a TV, any more than I have in a PC. If you're going to start talking about taking the PSU apart (which will often require drilling out rivets), that really is a different thing!

You didn't - but, as I implied, unless you're going to start thinking in terms of taking the PSU apart, I don't think you'll find any touchable 23OV mains when you take the back of an even half-modern TV.

Plasma TVs are packed with dangerous voltages, just recently I threw a Y SUS board across the room when it gave me a belt as I didn't discharge it fully.

The larger TVs have fairly hefty PSUs with often large areas of primary circuitry.

Have you thought about taking up Tarot reading JohnW2? You appear to have a talent for predicting what one is going to do before one does it :eek:.

I repaired one the other day which had a non isolated heatsink which is quite unusual now.

I edited that stupid comment out!
 
Thanks guys. Haeger switches are not an option as I have gone for the screwless fittings throughout. Based on the above, this leaves me with the option of wago connectors or the terminal blocks?

Also, with all the scare stories, can I please check that there are no issues with following this configuration?

The light cable will then connect to L, N and E terminals on the light.

I can do without any bangs on this occasion.
 
That's true, but other manufacturers might start following suit - since N looping seems to be becoming more fashionable, and there is no doubt that such switches make for a neater job in the hands of those who know what they are doing.

Kind Regards John

Clipsal switches also have loop terminals.
