Electrical connector with switch

Claim 1

An electrical connector comprising: an insulative housing and a selected number of contacts disposed therein extending from a mating face at a forward portion to a rear face, said contacts having respective first contact sections exposed along the mating face for electrical engagement with complementary contacts of a mating connector, and second contact sections exposed along said rear face and connectable to another electrical article; and a switch contact affixed to the housing remote from said mating face, said switch contact including a body section secured to said housing, a contact section extending from said body section and exposed for connection to said another electrical article, and a spring arm extending from said body section; said switch contact spring arm extending across said forward portion to a leading end and includes a contact-engaging section spaced from said body section and spring biased against a portion of a selected one of said contacts when the connector is in an unmated condition, said spring arm being spaced from all others of said contacts and said housing adapted to permit rearward deflection of said spring arm, and said switch contact further including a connector-engaging portion at least proximate said leading end to be abutted by a portion of said mating connector during final stages of connector mating, such that said connector-engaging portion is urged rearwardly to deflect said spring arm thereby disengaging said contact-engaging section from said selected one of said contacts, whereby a circuit is established by said second contact section of said selected one of said contacts and said contact section of said switch contact when said switch contact is engaged with said selected one of said contacts, and said circuit is interrupted upon mating by said mating connector.
