Question about using different triggers to change One set of booleans

So recently i started development on my first game. one of the area's in the game haz a puzzle in it with multiple doors being triggered by different chain's. The trigger part i have down but the way i have currently programmed it is that every seperate trigger object has a seperate script with seperate booleans.

How do i get these boolean's to be changed by all 3 trigger objects? Here is the start and update of my Trigger objects: void Start() { Activate = new BooleanDeciderClass(true, false, true, false); inTrigger = false;
}

 void Update()
 {
     if ((inTrigger == true) && (Input.GetKeyDown("e")))
     {
         Debug.Log(Activate.getEntrance());
         chainActivate();
         WheelActivate();
         ExecuteAnimation(Case, RightDoorObj, LeftDoorObj, EntranceObj, ExternalObj);
         Activate.CaseFunction(Case);
         Debug.Log(Activate.getEntrance());
     }
 }

Constructer of my boolean class:

public BooleanDeciderClass(bool LeftDoor, bool RightDoor, bool Entrance, bool External) { this.LeftDoor = LeftDoor; this.RightDoor = RightDoor; this.Entrance = Entrance; this.External = External; }

The Case function that is supposed to flip the booleans.

 public void CaseFunction(string CaseName)
 {
     Debug.Log("CaseTestTop");
     switch (CaseName)
     {
         case "Left":

             if (RightDoor)
             {
                 Debug.Log("CaseTestLeft");
                 RightDoor = false;
             }
             else {
                 Debug.Log("Is it coming here1");
                 RightDoor = true;
             }
             if (Entrance)
             {
                 Debug.Log("Is it coming here2");
                 Entrance = false;
             }
             else {
                 Debug.Log("Is it coming here3");
                 Entrance = true;
             }
             if (External)
             {
                 External = false;
                 Debug.Log("CaseTestExternal Left" + External);
             }
             else {
                 Debug.Log("CaseTestExternal Left2" + External);
                 External = true;
                 Debug.Log("CaseTestExternal Left3" + External);
             }
             Debug.Log("CaseTestExternal Left4" + External);
             break;
         case "Right":
             Debug.Log("CaseTestRight");
             if (LeftDoor)
             {
                 LeftDoor = false;
             }
             else {
                 LeftDoor = true;
             }
             if (External)
             {
                 External = false;
                 Debug.Log("CaseTestExternal Right" + External);
             }
             else
             {
                 External = true;
             }
             break;
         case "Entrance":
             Debug.Log(LeftDoor + "  " + RightDoor + "  ");
             if (LeftDoor)
             {
                 Debug.Log("Test");
                 LeftDoor = false;
             }
             else
             {
                 Debug.Log("Test2");
                 LeftDoor = true;
             }
             if (RightDoor)
             {
                 RightDoor = false;
                 Debug.Log("Test3");
             }
             else
             {
                 Debug.Log("Test4");
                 RightDoor = true;
             }
             Debug.Log(LeftDoor + "  " + RightDoor + "  ");
             break;

     }
 }

Thanks in advance! -derparuni
