Limit switch

From FIRSTwiki

A limit switch is a digital sensor. It has a value of open or closed, i.e., whether or not the switch lever has been hit to depress the switch on the sensor. It can be wired as normally open (NO) or normally closed (NC) to change how the values are interpreted.

On the Robot Controller a closed switch gives a 0 while an open switch gives a 1.
