Cheap shower pull switches?

Get a Crabtree 50A pull cord - never had a call back from one of those.

3 in a row is just improbable. Take one of the 'duff' switches and just measure the resistance across it.

More likely is a poor connection somewhere.

Probably at the DB if there is no hidden joints.

You tested and there was no voltage on the load side
Are you saying that both poles of all three pull cords have faulted ?

Disconnect circuit get your IR tester out, give it 500v a few times that should blow the HR joint if there is one lol.

The other thought that ran through what's left of my brain tonight was neons being wrongly wired.

Poor ****er probably cost more in time and petrol then the jobs worth, tho i would have gone with a different brand the second time, either dodgy batch/poorly made or you are the unluckiest person ever.

Good lesson here on why buying better quality accessories is a good idea.

Crabtree pull switches can stick. Ive only ever seen it once with my mentor at the time and it was very rare for him to see it.

There is a bit of plastic that pops out when it is on.

When it sticks it doesnt pop out but when you unscrew it and hold in your hand it works every time

Whats with these shower pull switches?
Any electric showers I've ever used, I just turn them on in the cubicle. There maybe an Isolation switch on the wall outside close to the light switch.
