| 1998 | Invention patented by Herve Guy Bricaud and Yves Pizard on December 7th, 1998. Abstract: A switch (12, in FIG. 1) for mounting on a circuit board (P), has a minimum number of parts and a very small height. The switch includes an insulative support (29) for lying on the circuit board and a switch element (33) with a pedal (58) extending above the upper face (18) of the support to be downwardly deflected by a card as the card reaches its fully installed position. The switch element is formed of electrically conductive sheet metal material, with a connect tab (43) for permanently engaging a first switch trace (25) on the circuit board, and with a contacting part (44) for lying over a second trace (26) on the circuit board. When the pedal is depressed, it also depresses the contacting part (44) to press it against the second trace to thereby close the switch. |
| 2001 | Invention patented by Jen-Jou Chang on March 5th, 2001. Abstract: An electrical connector (1) has a housing (10) receiving signal contacts (12) therein, a switch (14) for detecting full insertion of an electrical card (2), and a guide frame (13) supporting the card therein and slidably engaged with the housing. The switch includes a fixed contact (15) and a resilient contact (16), which are in contact with each other when the switch is in a normal position. The fixed contact has a contact piece (150) connected to a first switch trace (31) of a PCB (3). The resilient contact has a solder tab (161) connected to a second switch trace (30) of the PCB, and a spring arm (162) for contacting the contact piece. The guide frame has a wedge (136) for disengaging the spring arm from the contact piece when the card is fully inserted into the housing. |
