  • Patent number: 7331825
    Abstract: A stacked electrical connector has an insulative housing (1), a plurality of signal contacts (23, 26) and a pair of contacts (24, 27, 25, 28) retained in the housing. The housing defines a mounting surface (19) for mounting on a printed circuit board and a receiving space (12) for receiving a mating plug (9). The switch contact includes a base portion retained in the housing and a spring arm extending from the base portion. An insulative separator (245) is formed on one spring arm and projects into the receiving space. The separator is moveable in a plane vertical to the mounting surface. When the mating plug inserts into the receiving space, the separator rotates and drives one switch contact to connect with the other switch contact.
