Contactor problem

[Lurch]

I cant find the link now. But there was a picture in here of a cabinet with a sign that said something like "Opening this cabinet will result in certain death and a large fine"

That picture (or the text at least) has been around for ages.

Never seen a latching contactor, seen latching relays though, so appreiciate that it is more than possible for them to exist.

Just assumed if you wanted the latching functionally you'd use a latching relay to control a standard contactor, or just use a standard contactor and use a spare pole to latch akin to DOL.

Can see the advantage though if its a lighting board in an office and the staff complain about the 50hz hum

EDIT:

You didn't send a picture to the daily mail letters page recently by any chance, did you, Tony?

According to the official IEC vocabulary there is no distinction between a contactor and a relay.

So you can have bistable versions of a relay, which could just as easily be called a contactor.
