You needn't subclass from osg::Switch, you could just subclass from osg::Group and override the traverse(.) method to provide the decision about whether to traverse the subgraph or not. Another approach is manage the switching on/off at a higher level but use the NodeMask 0x0 or 0xffffffff as the two states for whether to rendering or not a subgraph.
