Twice in 2 weeks, faults caused just by normal handling of kit, ie gripping
at the edge to pick up the kit and pushing in some vital control component.
Only an inch or so in from an edge so precisely where a thumb could go on
picking up relatively heavy kit.

Previous was just an LED but was vital to use as not knowing what mode it
was in.
Again today , but this time an awkward to find a replacement and replace, on
a double-sided board, sub-miniature 2 pole 3 way slide switch. So weak that
the switch action was disrupted when pushed inwards with a thumb, leading to
crackle on one channel.

So especially with this replacement adding a protruding physical guard at
this switch and also at a similarly placed but functioning one.
And previously a guard ring around that LED.
