Abstract
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.
