SelectSwitch Control
This control is used to show a toggling button that shows a 'indicator' to indicate enabling and an optional piece of text to indicate the choice. The control is meant to be a replacement for ToggleSwitch which users tend to want to swipe instead of tap. This is especially problematic on Pivots or Panoramas. You can see the control here:

You can see the XAML here where the IsSelected property is the boolean value of whether the control is enabled or not. It is a ContentControl so what is on the right is inside the control:
<my:SelectSwitch IsSelected="{Binding SomeBoolean, Mode=TwoWay}"
x:Name="theSwitch">
<TextBlock Text="This is the content of my SelectSwitch control"
FontSize="24"
TextWrapping="Wrap"
FontWeight="Bold"
Margin="8" />
</my:SelectSwitch>
You can control what the text is on the control with individual attributes as well as what brushes are used for the text or the 'indicator':
<my:SelectSwitch IsSelected="{Binding SomeBoolean, Mode=TwoWay}"
SelectedText="Is Enabled"
UnSelectedText="Not Enabled"
TextIndicatorFontFamily="Comic Sans MS"
TextIndicatorFontSize="16"
TextIndicatorFontWeight="Bold"
TextIndicatorFontStretch="UltraExpanded"
TextIndicatorBrush="Green"
TextIndicatorFontStyle="Italic"
IndicatorBrush="Orange">
<TextBlock Text="This is the content of my SelectSwitch control"
FontSize="24"
TextWrapping="Wrap"
FontWeight="Bold"
Margin="8" />
</my:SelectSwitch>
