My Basic Coil Gun Setup

const int switchPin = 4;
const int Coil = 2;
const int Battery = 3;

int CoilState;

void setup() {
  pinMode(Coil,OUTPUT);
  pinMode(Battery,OUTPUT);
  pinMode(switchPin,INPUT);
  digitalWrite(Battery, HIGH);
}
void loop(){
CoilState = digitalRead(switchPin);

if (CoilState == HIGH) {
    // turn LED on:
    digitalWrite(Coil, HIGH);
    digitalWrite(Battery, LOW);
  } else {
    // turn LED off:
    digitalWrite(Coil, LOW);
    delay(2000);
    digitalWrite(Battery, HIGH);
          
  }
}
