When the first and second housings are fully engaged in this manner, the connector positive assurance member may be moved from a first position to a second position to assure complete engagement has been effected and to lock the housings together. If the first and second housings are not fully engaged, the connector positive assurance member can not be moved from such first position to such second position.

Abstract: A switch structure for a card connector comprises: a first cantilevered contact spring 20 urged so that a front engagement portion of the first contact spring engages a part of the recessed portion of the inserted card corresponding to one of two slide positions of a write protect button 3; and a second cantilevered contact spring 30 extending along and in the same direction as the first contact spring and urged so that a front engagement portion of the second contact spring engages a part of the recessed portion of the inserted card corresponding to the other slide position of the write protect button 3; wherein the slide position of the write protect button is detected based on whether the first and second contact springs are in or out of contact with each other, thereby determining the position of the write protect button accurately and reliably.

Abstract: A connector fitting construction in which a half-fitted condition is positively prevented when fitting a pair of female and male connectors together, and a connector-inserting force, required for the fitting operation, can be reduced. In this connector fitting construction, one of the two connectors has a slider receiving portion (4), formed by an exclusive-use housing (3b), and has a lock arm (6) on which a lock beak (7), having a slanting surface, is formed. A slider (10) has a pair of abutment projections (14) formed on a lower surface of a slider body (11), and a slide groove (13). The abutment projections (14) can be received respectively in side spaces (4a) provided respectively at opposite sides of the lock arm (6) within the slider receiving portion (4). The lock beak (7) can be fitted in the slide groove (13).
