Abstract
An audio jack comprises a set of contacts including a stationary contact (25) and a movable contact (23), and an anti-dust dome member (5). The anti-dust dome member (5) includes a conductive sheet (51) extending from a horizontal plate portion (250) of the stationary contact (25) to a lateral beam (235) of the movable contact (23), and a middle conductive dome sheet (52) below the conductive sheet (51). The conductive dome sheet (52) is constantly actuated to establish an electrical connection between the stationary contact (25) and the movable contact (23). Thus, even if dust is deposited on the anti-dust dome member (5) will have no effect on the electrical connection as established.
