Does the lever rotate in both directions?

Yes it is fully adjustable both 360 degrees on the shaft or by sliding on the slot on the lever arm.

can a diode be added to this switch?

This is a mechanical on/off limit switch that will work for a/c or d/c. Yes, you could add a diode in a circuit with this switch but that seems like an exotic function for this simple switch. I use them in a 110v a/c circuit stopping an elevator at each floor. I have never had a failure of one.

would this switch work with a raspberry pi raspberry pi?

Both Arduino and the Rasberry PI inputs are rated at 5V. It should work for the Rasberry PI.

are these waterproof?

Not claimed to be WATERPROOF, but ARE Weatherproof. Waterproof infers dunking in water whereas Weatherproof infers that its operation and reliability are NOT affected by dampness or occasional exposure to rain showers. After 3 years of operation, mine still works like it did when I installed it.
