Accordingly, the specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description. 
     The present teachings relate to a plug of a device and preferably an electrosurgical device. Preferably, the present teachings relate to a plug of an electrosurgical device and associated componentry that form an electrosurgical system. The plug may be connected to a device in an electrosurgical system that may include one or more hand pieces, one or more ground pads, one or more generators, one or more electrosurgical devices, one or more adjacent hand piece components, or a combination thereof each device which are incorporated into the electrosurgical system. The plug and electrosurgical device may be any device that may be used by a surgeon to perform a surgical procedure. The electrosurgical device may function to be switched between two or more configurations, two or more states, or both. For example, the electrosurgical device may be switched between a monopolar configuration, a bipolar configuration, a non-electrosurgical configuration, or a combination of the three. The electrosurgical device may be any device that may be switched between two or more configurations with one hand so that a user may switch between the configurations without the need for a second hand, without disrupting the procedure, or both. The electrosurgical device may be any device and/or configuration that may be used ambidextrously, ambidextrously switched between configurations, or both. The electrosurgical device may be used to cut, perform hemostasis, coagulate, desiccate, fulgrate, electrocautery, or a combination thereof. The electrosurgical device may be any device that includes bipolar capabilities, monopolar capabilities, non-electrosurgical capabilities, or a combination thereof.
