An audio jack comprises an insulative housing, a plug receptacle projecting from the housing for mating with a complementary audio plug, and a pair of transfer switches retained in the housing and extending therefrom for connecting to a circuit board. Each transfer switch consists of an engagement contact and a resilient contact engageable with the engagement contact. Each resilient contact comprises a contact portion with a wiping contact section formed thereon engageable with the corresponding engagement contact. A wiping contact action between the resilient contact and the corresponding engagement contact is complemented by the design of the wiping contact section to remove contaminants on the contact interface thereby ensuring a reliable connection therebetween.

A modular receptacle jack assembly with a visual indication function provides a visual indication when the receptacle jack is connected with a mating plug jack. The modular receptacle jack assembly comprises a modular receptacle jack and an indicator mounted to the jack. The jack includes a housing having a bottom wall for connection to a printed circuit board, a top wall opposite the bottom wall, a front face defining a cavity for receiving the mating plug jack and a rear face opposite the front face, and a number of contacts securely fixed to the bottom wall of the housing and having contact portions extending into the cavity. The indicator includes a base having a first wall attached to the top wall of the housing and a second wall attached to the rear face of the housing and defining holes extending lengthwise therethrough. Diodes are mounted on the base and have leads extending through the holes. A cover has a third wall connected to two side walls extending upward from two ends of the first wall and a fourth wall connected to the second wall. A transparent block is mounted between the first and side walls of the base and the third wall of the cover cooperating therewith to enclose the diodes.
