Question something very simple about camera in 3D games

i want that the camera change depends on the position of my "player", but im just started in this world and i dont know how this exactly works, i made this condicional that is called from update:
void camSelector() {
if (player.transform.position.x < 2.5)
{
cameras[0].gameObject.SetActive(true);
cameras[1].gameObject.SetActive(false);
camDirection(0);
}
else
{

cameras[1].gameObject.SetActive(true);
cameras[0].gameObject.SetActive(false);
camDirection(1);
}
}
but it is too fast am the character get stuck when the camera change because the cameras are facing each other, and the forward direction in one is the back direction in the other, so it's like a loop

 

2 things.

CONDITIONAL, and use CODE tags.
