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.
