Abstract
An electrical plug assembly may include a body having a plurality of electrical contact blades and an actuator. In particular embodiments, the plug assembly includes a shield member having a back and a front. The back has an opening arranged to receive the body therein and the front has a plurality of openings, wherein each opening is shaped, sized, and aligned with a respective one of the plurality of contact blades of the body. In a particular embodiment, the plug assembly further includes a biasing member positioned between the body of the plug and the back side of the shield member to operatively interact with the shield member to prevent electrical current flow and during operation the shield member may slide over the body and operatively engage the actuator to allow electrical current flow.
