These liquid level switches are
sealed with potting compound. The
only path for liquid to the electrical
switch would be through the wires.
If the wires are terminated in an
appropriate manner [e.g. NEMA 6
(IP68) connectors], the level switch
will meet or exceed a NEMA 6
(IP68) rating, making them suitable
for submersion with years of
worry free operation in moistureladen environments. A sealed
SPST switch provides consistent
accuracy and high repeatability with
the effects of shock, vacuum or
vibration minimized. The switch is
extremely versatile since it is user
selectable as a normally open or
normally closed by simply reversing
the float or the mounting of the
switch. The standard NPT male
fittings allow for quick installation in
either the top or bottom of the tank
or vessel.
