ToggleButton changes when I move from fragment to another fragment (BottomNavigationView)

I'm using bottomnavigationview with fragment ... the problem is that I turn on the togglebutton in "on" and when I select another item in bottomnavigationview and I select again the item where the togglebutton is hosted it goes "off"

Menu.java

public class Menu extends AppCompatActivity implements BottomNavigationView.OnNavigationItemSelectedListener{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_menu);

    BottomNavigationViewEx navigation = (BottomNavigationViewEx) findViewById(R.id.navigation_menu);
    navigation.setOnNavigationItemSelectedListener(this);
    loadFragment(new HomeFragment());
    navigation.enableAnimation(false);
    navigation.enableShiftingMode(false);
    navigation.enableItemShiftingMode(false);
}

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {

    Fragment fragment=null;

    switch (item.getItemId())
    {
        case R.id.navigation_home:

                fragment = new HomeFragment();

            break;
        case R.id.navigation_sala_espera:

                fragment = new SalaEsperaFragment();

            break;
        case R.id.navigation_consultorio:

                fragment = new ConsultorioFragment();

            break;
        case R.id.navigation_ajustes:

                fragment = new AjustesFragment();

            break;

    }

    return loadFragment(fragment);

}

private boolean loadFragment(Fragment fragment)
{
    if(fragment!=null)
    {
        getSupportFragmentManager()
                .beginTransaction()
                .replace(R.id.fragment_container,fragment)
                .commit();

        return true;
    }

    return false;
} }

SalaEsperaFragment.java

public class SalaEsperaFragment extends Fragment {


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View view= inflater.inflate(R.layout.fragment_sala_espera, null);
    final LinearLayout linearLayout=(LinearLayout)view.findViewById(R.id.ll_sala_espera);
    final ImageView imageView=(ImageView)view.findViewById(R.id.iv_sala_espera_foco);
    ToggleButton tb_foco=(ToggleButton)view.findViewById(R.id.tb_sala_espera_foco);

    tb_foco.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean isCheked) {
            if(isCheked)
            {
                linearLayout.setBackground(getResources().getDrawable(R.drawable.drawable_linearlayout_on));
                imageView.setImageResource(R.drawable.ic_foco_encedido);
            }else{
                linearLayout.setBackground(getResources().getDrawable(R.drawable.drawable_linearlayout_off));
                imageView.setImageResource(R.drawable.ic_foco_apagado);
            }
        }
    });

    return view;
} }
