I have just removed a knackered timer - the cheap rocker switch that selects "timed" "off" or "On" just wasn't capable of carrying the current - and the terminals of the switch were merely pushed into sprung leaves. All in all a very cheap inadequate construction (It was branded Focus - but bought off e-bay)
Can anyone recommend a suitable replacement? - it is to enable a daily dose of power during E7 period. Timing doesn't need to be sophisticated.
