Kit includes a pair of simple bumper switches custom built for the VEX Robotics Design System. Ruggedized Bumpers allow the switch to be triggered by large impacts without sustaining damage.

  - Provide feedback to Microcontroller as events "happen".
  - Rugged bumpers allow switch to be triggered without damage.
  - Useful as a trigger in a variety of applications.
  - Functionality is pre-programmed in the VEX Microcontroller.

Bumper Switch Sensor: The bumper sensor is a physical switch. It tells the robot whether the bumper on the front of the sensor is being pushed in or not.

Switch Info: SPST switch (“Single Pole, Single Throw”) configured for Normally Open behavior.

Signal Behavior: When the 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 switch is released. An unpressed switch is indistinguishable from an open port.
