When using my electric shower this morning I was aware of a slight
burning smell..It was coming from the shower pull switch. I found thst
I could not switch it off andd had to use the mains switch .
I do have a habit of leaving the pull switch on for long periods .Is
this inadvisable and could it have contributed to it's demise ..Is it
possible that the contacts have "welded " themselves together .It it
likely to be salvageable .??

Possibly

and could it have contributed to it's demise

No.

..Is it

Yes, but more likely the plastic parts supporting the contacts
have melted and can't hold them apart anymore.

It it likely to be salvageable .??

No.

You need a new switch. This switch carries high current -- get a
good one and not the cheapest no-name. One or more of the cable
ends could be damaged too (poor contact in one of the screw
terminals is a likely cause). If you replace it yourself, make
sure you make very good connections to the cable, or it will
happen again. Don't use the shower again until it's been
repaired -- it might catch fire, and will make the repair more
difficult in any case.

burning smell..It was coming from the shower pull switch.

Is it worth the house going on fire ?

I saw that a few minuts ago before reading your message .Even the MK
one is only about £12...I envisaged them to be much more expensive
....Could even get one of each as a spare .

What 'mains switch'?

Yes. The shower switch is an isolator, not a functional on\off switch.
Clamging it on and off and shoving 30A+ across it every time you take
a shower will do it more harm than leaving it switched on. I always
recommend to leave them switched on.

No.

Probably.

Nope.
