I think the main microswitches (the ones which switch the two elements,
controlled via the power dial) on my T80i shower are dead - or at least one.
(I resurrected one a few years back, but it's probably time to get new
ones).

I know they're available from Triton, but they appear to be fairly generic
microswitches and quite expensive for that - anybody got an idea of
appropriate replacements from elsewhere?

They will almost certainly be high current V3 microswitches (a standard
format) with plain button actuators. They are dead easy to get in 16A
versions but fewer suppliers have the 20A+ ratings that are sensible to
use in electric showers.

IME RS Components have the best range of these and I believe they do
allow one off web orders.

Last time I did this I used Cherry microswitches eg RS code 159-4477
(£2.17 + vat) but I see they have a Honeywell one that is cheaper and is
rated for high temperature use too, RS code 515-729 (£1.35 + vat)

Pop the lid to check how many the shower uses, some use a lot, and it's
easiest to get enough to replace the whole lot if needs be.

If the shower is getting long in the tooth, watch for overheating damage
on the loom going to the microswitches, the spade connections they use
are right on the limit at 20A and it doesn't take much to push them over
the edge into overheating. Make sure the spades are a really tight fit
on replacement.
