No, Switchblades are illegal for citizens to own in the united states. Only exceptions are if you are connected with law enforcement/government OR if you can in california in which they are legal but the maximum blade length is 2 inches.

Almost all states prohibit carrying any knife with a blade longer than 3 or so inches. And a switchblade is considered a dangerous weapon. Check the individual states for specifics, the link below gives a summary.
automatic knives are defined as having a blade which is deployed by simply pressing a button located on the handle of the knife. balisongs, or "butterfly" knives, consist of two handles that rotate around a blade at two pivot points. these knives don't have any sort of deploying mechanism or spring an are completely manual, they are not considered automatic knives. However, in some states, a butterfly knife is considered a switchblade because you can use gravity to open it. An example of such a state is New Jersey.
Why would they? A policemen would need a heavier duty blade-a switch blade simply would not suffice.
