what provides light to allow you to view materials on a glass slide?
It's a light source.
lightsource
it controls the amount of light let into the slide.
Stage
We don't answer questions from printed or copyrighted materials.
The Stage of a microscope has that little opening so that light can pass through the slide so you can see what's there. without it, you wouldn't be able to see the specimen on the slide.
The light in a room is captured on some models of microscopes by a mirror. The light passes through the stage opening and illuminates the specimen on the slide. The light is then focused by an array of lenses before exiting the eyepiece. Some models of microscopes use a light called an in base illuminator in place of a mirror that shines a bright toward the microscope's stage opening.
there is a miniature flash light inbeded into it
Most microscopes have a small lamp below the place where the glass slide is attached.
mirror
It depends on the design of the light microscope you are using. Modern microscopes use electric bulbs, but older designs use a mirror to reflect light from the Sun.

The diaphragm adjusts the amount of light
It depends on the design of the light microscope you are using. Modern microscopes use electric bulbs, but older designs use a mirror to reflect light from the Sun.
A light source, normally located under the iris diaphragm, can be over various strengths. The light source passes through the iris, through the condenser lens, to illuminate the stage.
Two types of microscope use two types of illumination. The old reflect mirror type use a mirror beneath the slide to gather light from the room and concentrate it on the slide. You wiggle the mirror around while looking through the 'scope until you get the brightest field. The second type of microscope uses an integral light source located beneath the slide. These are expensive, because the light must be as pure as possible and evenly bright across the viewing field.

Answering the LITERAL question, generally slide switches are soldered into a circuit. But to answer the question of what a 3 conductor slide switch can do for a circuit: A slide switch can allow the circuit designer to select between two choices, perhaps causing a switch to illuminate either the white light or the blue light. Since some slide switches only allow the two options, that would be all THAT slide switch could do. But other slide switches have other abilities, for them a center position allows the circuit designer to select between the two lights OR, but putting the switch in the center position, both lights would be off. Other slide switches include an internal resistor that allows for a fading effect, allowing for a light to be ON, OFF or some varying state between.
