A memory card connector includes a housing including an accommodation portion and contacts, a slider movable between an initial position and a fully-inserted position, a correct-insertion abutting portion and an incorrect-insertion abutting portion provided on the slider, and a stopper-switch leaf spring. A stopper is provided on the stopper-switch leaf spring, wherein the slider is allowed to slidably move from the initial position to the fully-inserted position when the stopper-switch leaf spring is positioned at a stopper-ineffective position, and the slider is prevented from slidably moving from the initial position to the fully-inserted position when the stopper-switch leaf spring is positioned at a stopper-effective position. The stopper-switch leaf spring and the stopper are positioned within the housing when the stopper-switch leaf spring is in a free state.
