Hello sorry for the previous message. Here is the code that I am working with.

const int switchPin = 2;
const int ledPin = 13;
const int relay1=7;
const int relay2=8;
int times=0; // how many times the wheel turns

void setup() {
  Serial.begin(9600);
  pinMode(switchPin, INPUT);
  pinMode(ledPin, OUTPUT);
  digitalWrite(switchPin, HIGH);

  pinMode(relay1, OUTPUT);
  pinMode(relay2, OUTPUT);

  digitalWrite(relay1, HIGH);
  digitalWrite(relay2, HIGH);
}

void loop() {
  if(digitalRead(switchPin) == LOW){
    digitalWrite(ledPin, LOW);
    times = times + 1;
  }else {
    digitalWrite(ledPin, HIGH);
    
  }

  /* Check the relay status */
  if(times==3) {
    digitalWrite(relay1, LOW);
  }else if(times==8) {
    digitalWrite(relay2, LOW);
  }
  
  Serial.println("Whell turn times:");
  Serial.println(times);
  delay(100);
}

Furthermore I have no schematics about my sensor. I just work with plug and play mode. The sensor is this: Keyes Hall Effect Magnetic Sensor Module for Arduino - Free shipping - DealExtreme
