Abstract

An electrical plug or similar device includes a plug body and a lever connected thereto adapted to reduce the force required to disengage the plug from a mating receptacle. The lever is suitably adapted to provide a mechanical advantage that decreases with the degree of rotation of the lever about its fulcrum. The arrangement is particularly described in relation to low profile plugs.
