Switch between 2 Characters with one input

Old discussion; but took me three days to work out "Character Switch" solution; so thought I would post my solution, in case it helps someone else. I am a beginner at coding; so it is possible my code could be more efficient; but it seems to work perfectly to switch between two characters. In my game, both players have a Main Camera and a Free Look Camera Rig. So those were some of the game objects that had to be switched. Here is the code I used...

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityStandardAssets.Characters.ThirdPerson;
 using UnityStandardAssets.Cameras;
 
 public class CharacerSwitch : MonoBehaviour
 {
     public GameObject player1;
     public GameObject player2;
 
     public GameObject cam3;
     public GameObject cam1;
 
     public GameObject rig1;
     public GameObject rig2;
 
     void Start()
     {
         player2 = GameObject.Find("Player2");
         player1 = GameObject.Find("Player1");
 
         cam3 = GameObject.Find("Camera3");
         cam1 = GameObject.Find("Camera1");
 
         rig2 = GameObject.Find("FreeLookCameraRig2");
         rig1 = GameObject.Find("FreeLookCameraRig");
 
         cam3.SetActive(false);
         rig2.SetActive(false);
 
         cam1.tag = "MainCamera";
         cam3.tag = "Camera 2";
     }
 
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.O))    //"O" for "Other" or "Other Player" 
         {
             if (player1.GetComponent<CapsuleCollider>().enabled == true)    //collider arbitrary, but reflects object state
             {
                 player1.GetComponent<Rigidbody>().isKinematic = true;
                 player2.GetComponent<Rigidbody>().isKinematic = false;
 
                 player1.GetComponent<CapsuleCollider>().enabled = false;
                 player2.GetComponent<CapsuleCollider>().enabled = true;
 
                 player1.GetComponent<ThirdPersonCharacter>().enabled = false;
                 player1.GetComponent<ThirdPersonUserControl>().enabled = false;
 
                 player2.GetComponent<ThirdPersonCharacter>().enabled = true;
                 player2.GetComponent<ThirdPersonUserControl>().enabled = true;
 
                 cam1.SetActive(false);
                 rig1.SetActive(false);
 
                 cam3.SetActive(true);
                 rig2.SetActive(true);
 
                 cam1.tag = "Camera 2";
                 cam3.tag = "MainCamera";
             }
         }
 
         if (Input.GetKeyDown(KeyCode.P))   //"P" for "Player" 
         {
             if (player1.GetComponent<CapsuleCollider>().enabled == false)   //collider arbitrary, but reflects object state
             {
                 player1.GetComponent<Rigidbody>().isKinematic = false;
                 player2.GetComponent<Rigidbody>().isKinematic = true;
 
                 player1.GetComponent<CapsuleCollider>().enabled = true;
                 player2.GetComponent<CapsuleCollider>().enabled = false;
 
                 player1.GetComponent<ThirdPersonCharacter>().enabled = true;
                 player1.GetComponent<ThirdPersonUserControl>().enabled = true;
 
                 player2.GetComponent<ThirdPersonCharacter>().enabled = false;
                 player2.GetComponent<ThirdPersonUserControl>().enabled = false;
 
                 cam1.SetActive(true);
                 rig1.SetActive(true);
 
                 cam3.tag = "Camera 2";
                 cam1 = GameObject.Find("Camera1");
                 cam1.tag = "MainCamera";
 
                 cam3.SetActive(false);
                 rig2.SetActive(false);
             }
         }
     }
 }
