simple question about on off switch

[AndrewT]

First, I mixed up english terms between neutral, ground & earth. Sorry for that, too much for my little german brain. I will now refer to the terms below (UK plug btw)

What I meant to say:
For class I equipment ( - and using isolation power transformers, the typical diy stuff - ) where the yellow-green earth is connected to the conductive housing, it is typically safest and most reliable to simply switch/break the mains loop on the primary side of the power transformer using a simple single pole switch.

I still disagree.

I disagree as well.

For much of our UK switching we are required to use two pole mains switches.
I can't recall the wording, nor to what classes of product this mandatory two pole applies to.

I'm just curious,

Can anyone list/name HiFi equipment which is mains powered that has no On Off switch?

Or amplifiers with no On/Off switch?

NB I'm not referring to equipment with the power switch on the back.
Perhaps just a standby function etc.

I can think of loads of TVs with just standby..and my Cyrus CD player.
I'm thinking about switching as a function/ convenience.

Don't have names, but there have been a few commercial phono preamps, etc.
lacking power switches, that were intended to be powered constantly.

I have a couple sub plate amps that just have stand by but no power switch. I can't remember the brand off the top of my head.

Any stereo receiver that operates with a remote controller is never really "off".

I can appreciate the safety aspects of the UK and EURO electrical codes, but the OP is in the USA, so they do not apply to him. regardless of how good the idea might be.
