Toggle switches to Analog board?

[sircedric4]

I know it is not a traditional use of the analog breakout board to attach toggle switches, as most people use potentiometers or some other sensors, but this year we have used up the 14 inputs on our Digital Sidecar. I have 4 questions before trying this and a search on here didn't pop up a solution.

1) Instead of adding a whole sidecar for the other 3 switches our current design needs, I was wondering if I could wire them to the Analog Breakout board instead? (I have to have an analog board for the battery jumper so I should go ahead and use it as much as possible and save some weight and failure points)

2) Do I need to have a resistor in the line between my switch and analog board, or can I strictly wire my switch to the analog breakout like I do the digital board, with just the white and black wire?

3) Has anyone done this before, if so what issues did you have?

4) Bonus question: Can I do the switch to the analog input on the driver station cypress chip as well, using the same method that I would hook it up to the robot analog breakout board?
