Limit Switch

Using Limit Switches to Control Behavior — FIRST Robotics Competition documentation

Limit switches are a type of sensor commonly used in FRC (FIRST Robotics Competition) to detect the physical position or limit of a mechanism or component. They are typically wired to the robot’s control system, such as the RoboRIO or a motor controller, and provide a digital input signal indicating whether the switch is open or closed.
