Limit Switch
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.
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.
