Following example shows how to bind data to switch inside the ListView and how to get toggled data on toggled event:
In xaml:

<ListView Grid.ColumnSpan="2" Grid.Row="1" ItemsSource="{Binding TaskList}" SelectedItem="{Binding SelectedTask}" >
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell >
                <StackLayout Orientation="Horizontal" >
                    <Label Text="{Binding TaskName}" />
                    <StackLayout Padding="150,0,0,0">
                        <Switch x:Name="chooseItem" VerticalOptions="Center" 
                                IsToggled="{Binding IsToggled, Mode=TwoWay}"
                                Toggled="Switch_Toggled" />
                    </StackLayout>
                </StackLayout>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

In cs:

private void Switch_Toggled(object sender, ToggledEventArgs e)
{
    try
    {
        var switchItem = (Switch)sender;
        var selectedTask = (SelectedTask)switchItem.BindingContext;
        //here you will get only toggled element model
    }
    catch (Exception ex)
    {

    }
}
