Abstract

An electrical plug-in option switch in which the orientation of the female plug while withdrawn from the associated male jack may be altered to select different circuit options. The plug is constrained by a supporting flange so that its orientation can be altered only when it is fully withdrawn from the jack. In addition contact between the plug and jack is possible only when the pins and sockets are aligned thereby preventing inadvertent damage to the pins during selection of the electrical option.
