Microswitch

➠ Use

The microswitch is usually used to keep something from overextending or surpassing some distance. When the switch not pushed, the switch is NC (normally closed), returning 1. When the switch pushed, the switch is NO (Normally Open), returning 0.

➠ Wiring

The switch is plugged into the Digital IO section of the roboRIO via a PWM cable.

➠ Programming

Declared and instantiated as a DigitalInput

• When switch NC, returns 0
• When switch NO, returns 1

Declaration: DigitalInput switch;

Instantiation: switch (1) //port number in the digital sidecar

Using Microswitch: switch.Get(); //returns either 0 or 1

// A Barebones Code
