That's not really true. Sounds like you had a particular switch that
could be positioned in between, in an unstable position. Some switches
have a center-off and if they do, it's clearly a detent position and
the switch is spec's as having a center off. If they don't then I guess
it depends on the design, how easy it is to get it into a position it's
not really meant to be in.
Why consider "unstable" to mean not there? An OFF position is a
necessary consequence of the switch breaking one connection before
establishing the other connection.
