1. A device for switching a surgical microscope into and out of multiple working modes, the surgical microscope defining an observation beam path and having a light source defining an illumination beam path for irradiating an object viewable via said observation beam path, said surgical microscope further having an eyepiece or observation instrument arranged in said observation beam path, said device comprising:
an observation rotary member defining a first rotational axis and being arranged in said observation beam path;
an illumination rotary member defining a second rotational axis transverse to said first rotational axis and being arranged in said illumination beam path;
a gear assembly connecting said rotary members directly to each other so as to permit said rotary members to rotate synchronously among a plurality of rotary positions corresponding to respective ones of said working modes;
said illumination rotary member having a plurality of first light-through-portions for passing light at each of said rotary positions from said light source through one or more of said first light-through-portions along said illumination beam path to irradiate onto said object; and,
said observation rotary member having a plurality of second light-through-portions for passing said light irradiated on said object along said observation beam path through one or more of said second light-through-portions to arrive at said eyepiece or observation instrument.
