- said switch body portion projects forwardly and beyond said second side of said contact body portion, from said intersection location;
- said surface mount terminals lying at the front and rear of said contact body portion, and said switch includes a pair of switch surface mount terminals lying at the front of said switch body portion.
- 4. An electrical connector for mounting on a read/write device, to connect to a microcircuit card that has a lower face with contact pads thereon, comprising:
- a contact body portion which has an upper face;
- a plurality of contacts mounted in said contact body portion, said contacts having resiliently deflectable blades that project above said contact body portion upper face, with said contacts having terminals for terminating to a circuit board;
- a switch body portion which has an upper face;
- a switch mounted on said switch body portion, said switch including an actuator with a portion projecting above said switch body portion upper face, and said switch including a plurality of terminals for terminating to the circuit board;
- said contact body portion and said switch body portion being integrally molded with their upper faces being coplanar;
- said contact body portion has a largely rectangular shape as seen in a plan view, with front and rear ends and first and second opposite sides, said contact body portion having an intersection location at the intersection of said front end and said second side;
- said switch body portion projects forwardly and primarily beyond said second side of said contact body portion, from said intersection location, so said switch body portion is offset from said contact body portion, with said actuator lying forward and to one side of said contact blades.
- 5. An electrical connector for mounting on a board of a read/write device that connects to a microcircuit card that has a lower face with contact pads thereon, comprising
- a body which includes a contact body portion which has an upper face and a switch body portion which has an upper face, with said body portions being integrally molded and being joined at an intersection location;
- a plurality of contacts mounted in said contact body portion, said contacts having resiliently deflectable blades that project above said contact body portion upper face, with said contacts having terminals for terminating to said board;
- said terminals are surface mount terminals with solderable ends that lie in substantially a horizontal plane when said contact body portion upper face lies in a horizontal plane;
- a switch mounted on said switch body portion, said switch including an actuator with a portion projecting above said switch body portion upper face to detect the front end of a fully installed card;
- said contact body portion has a largely rectangular shape as seen in a plan view, with front and rear ends and first and second opposite sides, said intersection location lies at the front end and second side of said contact body portion;
- said switch body portion projects forwardly and beyond said second side of said contact body portion, from said intersection location;
- said switch includes a pair of switch surface mount terminals having solderable ends that lie substantially in said horizonal plane.
- 6. An electrical connector for mounting on a circuit board, where the circuit board lies in a horizontal board plane and has board conductors, where the electrical connector is designed for engaging card contact pads on a face of a card that lies in a horizontal card pad plane, comprising:
