Anyone else finding faults due to normal handling ?

[N_Cook]

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.

Could there be excessive vibration during transportion weakening things and
then a small bump breaking them?

Just about every battery compartment lid on any battery powered

There are a few electronic devices with batteries that use a tab on
one end and a screw on the other end, those covers seem to hold up ok.

I've seen some large CRT TV sets, where if you set them down in a
forward-tilted position (IOW set the front edge down first), the front
of the plastic base breaks off. To me that's ridiculous, to require
handling so carefully that one must set the unit down almost perfectly
flat or something will break off....

Thats that wonderful chinese engineering and construction. ;-)

Probably 'construction', but the last time this happened to me, it was a
Sony Trinitron 30(?)". I assume this was designed in Japan.
