Abstract: This invention relates to an electrical connection device including a male component or plug having a plurality of connection pins extending outwardly therefrom. The electrical connection device also includes a female component or socket body having--(i) a plurality of recesses contained therein;(ii) a plurality of contact members wherein each contact member is associated with a respective recess;(iii) a plurality of connection terminals; and(iv) switching means.The arrangement is such that each connection pin of the male component may be inserted in a mating recess of the female component and thereby engage with an associated contact member wherein after a rotational or pivoting movement of one component relative to the other this may cause movement of the switching means to effect electrical connection between each contact member and an associated connection terminal.
