Abstract: A card connector 1 includes a slide member 21 movable along an inserting/withdrawing direction of a card, an urging member 22 for urging the slide member 21 toward a card insertion opening, and a pin member 26 having a slide end 26a slidable within and relative to a cam groove 25 provided in the slide member 21 and a support shaft end 26b supported to the body 2 side. As the slide end 26a is retained at a lock portion L formed in the cam groove 25, the card is retained at an appropriate position. The card connector 1 includes a switch mechanism M which is operated by the support shaft end 26b when the slide end 26a is pushed by the slide member 21 along the urging direction of the urging member 22 at the time of retention of the slide end 26a at the lock portion L.

Abstract: A key switch comprises: a plurality of conductive portions which are respectively positioned in dispersed directions from a center of a key top; and contact patterns provided on a print substrate, which respectively face the conductive portions. The contact patterns each have, in a conductive portion facing area thereof, at least four separate lands, and the at least four lands include: a first land and a second land which are separated by a first gap provided on a first reference line which extends from a position facing the center of the key top in the direction of the center of the conductive portion facing area; a third land which is separated from the first land by a second gap provided at a position which is distant from the first reference line in one direction; and a fourth land which is separated from the second land by a third gap provided at a position which is distant from the first reference line in another direction.
