Low profile connector

An electrical connector, comprising:

• a housing having a front side and a rear side which are opposite and a spacer;
• a cage engaged with the housing, the cage and the housing together defining a first slot and a second slot positioned respectively above and under the spacer, and an entrance of the first slot and an entrance of the second slot being adjacent to the front side so as to respectively allow an electronic card to enter into and exit from the first slot and the second slot along a card insertion direction;
• a first detection switch provided to the housing and adjacent to a side of the first slot, the side extending along the card insertion direction, and the first detection switch comprising:
• a first resilient terminal having a first fixed portion fixed to the housing and positioned outside the first slot, a first resilient arm portion extending from the first fixed portion toward the rear side and offsetting toward the first slot, and a first end portion extending from a distal end of the first resilient arm portion and extending into the first slot and adjacent to the rear side;
• and
• a second resilient terminal having a second fixed portion fixed to the housing and positioned outside the first slot, a second resilient arm portion extending from the second fixed portion toward the rear side and offsetting toward the first slot, and a second end portion extending from a distal end of the second resilient arm portion, the second end portion being further adjacent to the front side relative to the first end portion, and when the electronic card is not inserted into the first slot, the second end portion contacting the first resilient arm portion, when the electronic card is received in the first slot, the first end portion being pushed by the electronic card and driving the first resilient arm portion so as to allow the first resilient arm portion to be separated from the second end portion;
• and
• a second detection switch provided to the housing and adjacent to a side of the second slot, the side extending along the card insertion direction, and the second detection switch comprising:
• a third resilient terminal having a third fixed portion fixed to the housing and positioned outside the second slot, a third resilient arm portion extending from the third fixed portion toward the rear side and offsetting toward the second slot, and a third end portion extending from a distal end of the third resilient arm portion and extending into the second slot and adjacent to the rear side;
• and
• a fourth resilient terminal having a fourth fixed portion fixed to the housing and positioned outside the second slot, a fourth resilient arm portion extending from the fourth fixed portion toward the rear side and offsetting toward the second slot, and a fourth end portion extending from a distal end of the fourth resilient arm portion, the fourth end portion being further adjacent to the front side relative to the third end portion, and when the electronic card is not inserted into the second slot, the fourth end portion contacting the third resilient arm portion, when the electronic card is received in the second slot, the third end portion being pushed the electronic card and driving the third resilient arm portion so as to allow the third resilient arm portion to be separated from the fourth end portion.
