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 that are triggered. These switches are great for signaling when a robot arm has reached the top or bottom of it's motion.
- 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
Overview
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.
