Abstract
An electrical jack (10) for use on a circuit board (47) is disclosed. Jack (10) has vertically stacked receiving passages (14) and (16) for plugs (18) and is protected against dust and other environmental contaminants by a cover (30). Jack (10) includes a common sleeve spring (20) for both plugs (18). First and second switching mechanisms (22, 24) function with lower plug (18), while third and fourth switching mechanisms (26, 28) function with higher plug (18). Lower ring and tip springs (116, 120) provide contact force about orthogonal tension axes. Pairs of retention lugs (122, 164) cooperate to hold jack (10) to circuit board (47).
