i had to replace a crabtree the other week. it had gone O/C. then again, i had fitted it in 2004 and the client had been using it as an on/off switch for 15 years, so can't crumble.
That's half the battle,Joe public treating a shower switch as they would a light switch,try get them to leave it well alone
I tell them if it was a wall switch hidden by junk in the back of a pantry ,are they going to empty the pantry to operate it, they then get surprised when the ends get fried
The round ones have two screws per terminal (bar the cpc termination).There are 2 versions click do, the ones similar to crabtree and the square faceplate version. The square faceplate version has 2 screws per terminal.

The MK 3ph cooker switches are fitted to the back box before wiring, a much nicer design! Though you do have to wire the neon indicator in yourself...
they won't loosen if you fit them right in the first place..13A mains sockets should use the same method. There would be no more risk of loosening connections when pushing the sockets back then.

Bring back the Tenby Pilot range!13A mains sockets should use the same method. There would be no more risk of loosening connections when pushing the sockets back then.

It is a switch, it should be capable of being switched on and off regularly, that's the whole point of it being there.
What's the point in installing an ugly pull switch in a bathroom if you can't even use it? They obviously aren't any use for safe isolation as they can't be readily locked off.
They are there for purposes of maintenance not as continuous load carrying means of switching
For the likes of some disabled showers,they even advise against doing so in the manufacturers user instructions,for showers without a start solenoid they cause it to make and break whilst carrying full the load ( its no wonder they regularly fail in the manner they are used)
My advice would always be given that the purpose of the switch is a means of isolation,any other use is likely to reduce the life significantly irrelevant of whether a pull cord looks ugly or not
It is a switch, you are even calling it a switch, if it is not for switching then why is it there at all? If it is just for maintenance why don't they have a means of locking off so that they can actually be used as an isolator?
How is the user supposed to switch the appliance off when they are not using it?
I think their description are as a shower isolator at point of sale though right? Haven't baught one in a long long time. There is a functional switch on the shower unit itself.
This brings another question though, are people getting out of the shower and pulling the shower cord rather than pressing the button on the shower unit?
If they are using the button on the shower, the isolator "shower switch" shouldn't be breaking or making a circuit with any load.
I see this most in control panel isolators, an people the majority of the time using the wrong colours.
Black and grey isolator handle, is only designed to take the operational current of the control system. Not to be used to switch off or on under load.
Red and yellow, can be used as a functional switch to disconnect or connect the control system on load. An as such will be rated appropriately for this.
