Switch for detecting the presence of a smart card in a read-write device

摘要

The invention provides a switch (12) intended to be mounted on a printed-circuit board (P), of the type comprising a case (29) and means for actuating the switch which comprise an elastically deformable control blade (32), a first end (37) of which is embedded in a case (29) of the switch and the second end (42, 44) of which engages with a device (26) for tripping the switch, and which comprise a lever (34) for actuating the control blade (32), characterized in that the control blade is a conducting blade (32), the first end (37) of which is extended by a finger (43) for electrical connection to a conducting track (45) of the printed-circuit board (P) and in that, when the card (C) is present, the second end (44) of the control blade (32) engages with another conducting track (26) of the opposite upper face (13) of the printed-circuit board (P). <IMAGE>
