Why do houses have a switch to turn the shower off,
either a cord on the ceiling or a switch in the hall?

Because that's how your stupid regulatory
authoritys decided it must be done.

At least you agree it's stupid.

Can't be for safety

Fraid so.

But it doesn't make anything safer.

Yes it does, because if you choose to switch that switch
when dripping wet, you wont get electrocuted when that
switch is switched by pulling on a cord to that switch.

- if you're in the shower and get a shock, if you've managed
to get out to reach the switch, you've got away from it anyway.

Its done like that for the other situation, so you
don't get out of the shower dripping wet and use
the switch dripping wet and get a shock that way.

What switch?

The one that you switch by pulling on a cord.

I'm, saying there shouldn't be any external switch anywhere.

There has to be one somewhere to turn
it off when the one in the shower fails.

Everyone turns the shower off on the shower itself while they're still in
it.

But when that fails you can't.

Can't be to isolate to work on it, there's a fusebox for that.

Correct.

Don't need to turn it off when you're finished
showering, there's a switch on the shower itself.

But that's one that can be safely used dripping wet.

And so can the one on the shower, because that's already splashed to hell
while you wash.

But its designed to be used wet.

So if you want to adjust the temperature, do you actually get out, turn
off the isolation switch, then change the temperature, then turn it back
on and get back in? The controls on a shower are waterproof!

And the one attached to the string you pull isnt.
