Provided is a one body-type power transfer switch, in which a disconnecting portion is integrally formed to reduce errors arisen due to accumulated assembly tolerance and simplify manufacturing processes, thereby improving operators' convenience. The one body-type power transfer switch includes a normal power terminal or an emergency power terminal which are respectively formed at upper portions of sides of the one body-type power transfer switch, wherein the normal power terminal receives power from a substation, and the emergency power terminal receives power from an emergency generator, a module including a load terminal formed at a lower portion of a side of the module so as to be spaced apart from the normal power terminal or the emergency power terminal, wherein the load terminal is used to supply power supplied from the normal power terminal or the emergency power terminal to the outside of the power transfer switch, and a moveable contactor that is selectively connected to the normal power terminal or the emergency power terminal, wherein the module is formed using an injection molding method, and side walls are integrally formed to have insulating power between power terminal connecting portions and a load terminal connecting portion so that the power terminal connecting portions and the load terminal connecting portion do not electrically contact each other.
