Shower Mixer Tap (1 Viewer)

[Figaro]

Hi, my shower mixer has stopped activating the pump although the tap was only replaced 14 months ago. I had the multi meter on it and there is current to the connections below the tap.
I guess it looks like the switch has failed ?
Can the switch be replaced or is there any other likely sources of the failure ?
TIA

Take a picture of the micro switch, I might have one that will fit

if u can get the mixer tap out u may be able to pull the microswitch off and lubricate it. switch cleaner would be best but WD40 or silicone spray might help.

I'll remove the tap later and have a look at the switch

Very common for the wire to the micro switch to get trapped and cut through, easy to repair if you are a dab hand with a soldering iron. Last van it happened a couple of times on kitchen tap, I soldered it and insulated it with 1mm silicon sleeving.

Whoops - ignore this - I confused you with another Hymer owner that I replied to earlier today.
Sorry

A switch is simply a mechanical device that touches and separates two bits of metal. You can test it by shorting the two wires that go to the switch.

If the water pump works as you touch a piece of wire/metal across the two wires, and stops when you don't, you've proved that the problem is the switch or the wires leading up to it.

OTOH, if it doesn't make the pump work, then your problem is not the switch but must be somewhere else.

I dismantled it all today, cleaned and sprayed with silicone lubricant, assembled and all seems to work fine now, and I now know where the micro switch is
Thanks for replies
