                <Ellipse Width="20" Height="20" Fill="{DynamicResource PrimaryBrush}" StrokeThickness="1" Stroke="{DynamicResource BorderBrush}"/>
            </Border>
        </hc:StatusSwitchElement.CheckedElement>

        <Border Width="80" Height="30" CornerRadius="0" BorderThickness="1" BorderBrush="{DynamicResource BorderBrush}">
            <Ellipse Width="20" Height="20" Fill="{DynamicResource BorderBrush}" StrokeThickness="1" Stroke="{DynamicResource BorderBrush}"/>
        </Border>
    </ToggleButton>

        <hc:StatusSwitchElement.CheckedElement>
            <Border Width="60" Height="20" CornerRadius="0" BorderThickness="1" BorderBrush="{DynamicResource BorderBrush}">
                <Ellipse Width="20" Height="20" Fill="{DynamicResource PrimaryBrush}" StrokeThickness="1" Stroke="{DynamicResource BorderBrush}"/>
            </Border>
        </hc:StatusSwitchElement.CheckedElement>
        <!--Default-->
        <Border Width="80" Height="30" CornerRadius="0" BorderThickness="1" BorderBrush="{DynamicResource BorderBrush}">
            <Ellipse Width="20" Height="20" Fill="{DynamicResource BorderBrush}" StrokeThickness="1" Stroke="{DynamicResource BorderBrush}"/>
        </Border>
    </ToggleButton>
<!--显式设定选中状态下隐藏默认内容元素-->
<ToggleButton IsChecked="True" Style="{DynamicResource ToggleButtonCustom}" hc:StatusSwitchElement.HideUncheckedElement="True" Margin="5">
        <!--Checked-->
        <hc:StatusSwitchElement.CheckedElement>
            <Border Width="60" Height="20" CornerRadius="0" BorderThickness="1" BorderBrush="{DynamicResource BorderBrush}">
                <Ellipse Width="20" Height="20" Fill="{DynamicResource PrimaryBrush}" StrokeThickness="1" Stroke="{DynamicResource BorderBrush}"/>
            </Border>
        </hc:StatusSwitchElement.CheckedElement>
        <!--Default-->
        <Border Width="80" Height="30" CornerRadius="0" BorderThickness="1" BorderBrush="{DynamicResource BorderBrush}">
            <Ellipse Width="20" Height="20" Fill="{DynamicResource BorderBrush}" StrokeThickness="1" Stroke="{DynamicResource BorderBrush}"/>
        </Border>
    </ToggleButton>

以上两个属性，组合使用，能够简单的控制选择类控件状态的展示功能，可根据以上案例进行合理调整
