When I write an article and save it, I want to verify my text. I don't want publish my article immediately. If I'm tired, I sometimes forget to disable the Lightswitch 'Status'. So, how can I disable it by default?
If you're using a Craft Client or Craft Pro, you can save your entry as a draft and review it later.
This isn't foolproof either. If you wanted to really try to restrict yourself, you could set up another user account that doesn't have privileges to "Publish live changes."
But again, this would require either a Craft Client or Craft Pro license.
