One of each pair of metal pieces making up each of the switches SW , SW is formed in the metal upper housing to reduce the number of parts of the switches arranged in the connector and to efficiently arrange these switches in a small space.

Card connector

A predetermined contact pressure required between the two metal pieces when they are come into contact with each other is produced by a pressing force of the two metal pieces acting in the direction of height or width of the connector . This arrangement prevents the inserted card from coming off and reliably and stably holds the inserted card.

Card detect switch for card connector

In an IC socket in which IC leads of an IC package are pressed down by a presser member so as to be contacted with and retained by contacts arranged on the socket, an IC socket for an IC package comprises an IC mount which is upwardly and downwardly movably interposed between the socket and the presser member. The IC mount is formed with through-holes or through-grooves, and the contacts each having a vertical slit are inserted into the through-holes or through-grooves. The IC leads of the IC package placed on the IC mount are pressed down together with the IC mount by the presser member such that distal end portions of the contacts are relatively protruded upwardly from the through-holes of the IC mount as the IC leads are pressed down, so that the IC leads are pushed into the vertical slits.
