VEX Limit Switch (2-pack)

Kit includes a pair of simple limit switch sensors custom built for the VEX Robotics Design System. Switches send a signal to the Microcontroller when they are triggered. These switches are great for signaling when a robot arm has reached the top or bottom of its motion.

Limit Switch Sensor Signal: The limit switch sensor is a physical switch. It can tell the robot whether the sensor’s metal arm is being pushed down or not.

Switch Type: SPDT microswitch, configured for SPST Normally Open behavior. Behavior: When the limit switch is not being pushed in, the sensor maintains a digital HIGH signal on its sensor port. This High signal is coming from the Microcontroller. When an external force (like a collision or being pressed up against a wall) pushes the switch in, it changes its signal to a digital LOW until the limit switch is released. An unpressed switch is indistinguishable from an open port.

Provide feedback to Microcontroller as events "happen".
Bendable sheet metal switch "arm" is very versatile.
Useful as a trigger in a variety of applications.
Functionality is pre-programmed in the VEX Microcontroller.
