More than likely the difference between DC amps and AC amps. MostJohn said:Well, it appears to be related to inductive switches - a European
standard. Perhaps it means 10A surge, 3A continuous load (vacuum
cleaner, etc).
Hunting for Pronic r30 t85 switch didn't turn up much, but enough to
make that guess after some refinements in the search.

switches handle less DC amps at the same voltage. This is due to the
lack of no interrupts you normally get with AC which works better to
quench the arc (Plasma).
But then again, don't listen to me, I am a farm boy, born where every
one is related.

Absolutely incorrect..legg said:The AC symbol follows the dual rating. If it were a DC rating, the DC
symbol would appear.

Possible multiple markings for this switch are listed.
Manufacturer ratings have little to do with the requirements for the
markings of certified components. There are likely different part
numbers that cover varying labeling requirements. These markings are
informative,only - but they must not misinform. A DC marking will have
the appropriate DC symbol.
The important marking is actually the identifying part number of the
manufacturer's part - that can be cross-related to the safety file's
paperwork at any time, for current information.

We buy switches all the time that are stamped that way.. if you look
at the catalog directory on the switch, you'll see the DC rating which
follows the same markings.
Not saying that switch he has is also following that rule but,
switched (many of them) are marked that way with no DC indicator on the
body, mainly because their isn't enough room to do so.

I don't think you get it. No surprise.
