Abstract
An interchangeable plug device includes a casing, an electrical plug detachably mounted in the casing and movable between a detached and an operative position, and a releasable locking mechanism designed to engage the electrical plug to maintain the plug in an operative position. The locking mechanism can be released by a user to allow the plug to be moved to the detached position. A preferred form of locking mechanism is a depressible lock bar connected to or integral with an electrical plug body, which is designed to engage a detent in a casing. A preferred form of electrical connection between a detachable plug and casing comprises a submerged pin and sleeve configuration to protect the user or passerby from electric shock. A preferred form of conducting prong is collapsible within the carrier and is securable in an extended position to avoid inadvertent collapse. A variety of interchangeable electrical plugs can be fitted to the same casing. A power supply may be fitted within the casing, allowing an electrical device to be attached to the interchangeable plug device.
