ABSTRACT:
An electrical card connector includes a rectangular dielectric housing having a front side from which a card is horizontally inserted into the connector, a rear side opposite the front side, a lower wall interferentially engaging with a number of contacts and defining a card receiving space above the contact passageways and an upper wall opposite the lower wall. A spring lever is integrally formed with the housing, having a free end located about the rear side of the housing, a root connecting with the housing, and a ramp extending upwardly and rearwardly from the root through the card receiving space to the free end. When the card is inserted into the connector, a leading edge of the card runs through the ramp of the spring lever to depress vertically the free end thereof. The free end in turn depresses vertically a movable part of a switch device in the housing to cause the switch to shift from a state to a different state. Thus, a condition that the inserted card reaches a position to electrically engage with the connector is determined.
