The switches do go bad,
Replacement switches are readily available,
And yes, some brake fluid will dribble out the hole when you remove the old switch. It will not drain your master cylinder, however, unless you step on the brake pedal while you have the switch removed.
After you've made the swap, check your brake fluid, add fluid if necessary, and bleed the brakes.
Remember, do not overfill your master cylinder. I chased a non existent leak for six months because I kept over-filling the master cylinder. It would run down the side and collect in droplets on the brass "Y" fitting.
: I believe the brake light switch on my master cylinder might be bad.
: Will removing the old switch drain the master cylinder?
: I'm new to these beasts and my manual doesn't say anything related to this. It just says something to the effect of "...replace if necessary..."
: Just want to make sure I'm prepared for some brake bleeding if need be.
