Determines whether the new value of the Switch.Value property can be parsed as a Boolean value.
The BooleanSwitch.OnValueChanged method determines whether the new value is a valid string representation of a Boolean value ("false" or "true"). If so, the method sets the Switch.SwitchSetting property to 0 or 1. Otherwise, the base method is called, which converts the string value to an integer value, which is then used to set the Switch.SwitchSetting property.
