Well the switch shyould turn off the sound, but the notifications should still appear. This is the way it was in the past and is the way that it should be. But, to answer your question, no the switch was not on orange. Everything is set for them to work, but I just never get notified. It's only when I manually go into an app that all of a sudden the notifcations appear. (I don't see badge icons either).By chance, is the little switch on the upper left side showing an orange stripe? If so, it has muted your phone's alerts.
