CAMERAS ERROR , I NEED HELP

I have a character with a collider, there are 2 objects: -Player -Object1 .CameraObj1 -Object2 .CameraObj2

I want than if the collider OnTriggerStay2D with one of the objects and I press TAB key change to de CameraObj from de Object I focus and if I am OnTriggerExit2D I return to the main camera. But when I stay in Object1 and I press TAB it puts the both cameras on CameraObj1 and CameraObj2 and there are a lot of errors. It shows the wrong camera and is made a mess with the cameras CameraObj1 and CameraObj2.

Please help.

This is my script I use the same script for both objects changing the Tags:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class CamerasFishes : MonoBehaviour {

 Camera MainCam;

 public GameObject Fish;
 public Camera Cam;
 bool Conect= true;
 private Collider2D currentCollider;


 void Start(){
     MainCam = Camera.main;
 }


 void CamFish(){

     if (Input.GetKeyDown (KeyCode.Tab) && Conect == true && this.gameObject.tag == ("ANGLER") )  {
         Debug.Log ("ON CAM TAG : " + tag);

         MainCam.enabled = false;
         Cam.enabled = true;
     } 
     else if (Input.GetKeyDown (KeyCode.Tab) && Conect != true && this.gameObject.tag == ("ANGLER")) {
         Debug.Log ("OFF CAM TAG  : " + tag);

         MainCam.enabled = true;
         Cam.enabled = false;
     } 
 }



 void OnTriggerEnter2D(Collider2D ANGLER){
     Debug.Log ("ENTER TAG  : " + tag);
 
     if(gameObject.tag == ("ANGLER")){
         Debug.Log ("ENTER LIGHT");
         this.currentCollider = ANGLER;

     }
 }


 void OnTriggerStay2D(Collider2D ANGLER){
     Debug.Log ("STAY TAG  : " + tag);

     if(gameObject.tag == ("ANGLER") && this.currentCollider == ANGLER){
         Debug.Log ("STAY LIGHT");
         Conect = true;
         CamFish ();


     }


 }

 void OnTriggerExit2D(Collider2D ANGLER){
     Debug.Log ("EXIT TAG : " + tag);

     if(gameObject.tag == ("ANGLER") && this.currentCollider == ANGLER){
         Debug.Log ("EXIT LIGHT");
         Conect = false;
         CamFish ();

     }


 }
