says this marking is according to the European standard EN 61058-1 and
means 10 A resistive, 3 A "motor", 250 V AC. The micro symbol might
mean "microdisconnection, contact gap < 3 mm", and the T85 might mean
that it is temperature rated to 85 C.
There is no further explanation in that document as to what "motor" load
means - higher inrush current, different power factor, etc. Googling
around finds a suggestion that for EN 61058-1, "motor" load means a
power factor of about 0.6, and that the switch can handle an inrush
current of six times the rating (18 A in this case).
I hope this helps!

Switches are always derated in DC usage due to plasma destruction.

pretty close to what it is..

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.
