Bumper Switch
Bumper Switch - Application

Bumper Switch (2-pack)


Kit includes a pair of simple bumper switches custom built for VEX Robotics. 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

Product Description

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.
Benefits:The bumper switch can help the robot avoid dangerous collision automatically.
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.
Range Limits: Forces less than a pound can trigger the Bumper Switch (5.06 oz typical).

The bumper switch can allow a robot to navigate autonomously by avoiding hard collisions, such as hitting a wall. For example, a robot can be programmed to briefly freeze when the Bumper Switch is activated, and then reorient itself so that it is no longer driving towards the obstacle.
