I have re-read your posts carefully,
and i think that your switches are to indicate
that the bladders are inflated,
and that they move about in some way, causing the
cord to fail regularly.
I take it you want to tell that the bladders are
inflated without any trailing wires which could fail.
Have you considered having a length of tubing like
that on a fishtank pump over to a stationary switch
from the bladder(s),
the stationary switch could be operated by a diaphragm.
Such small bore plastic tubing is very sturdy and
flexible, i would think it could flex for a very long
time before sustaining any damage.
Still thinking about this.
Could you give me some more details of the set-up or
arrangement you are using please.
Does it involve water and things that float ?
