Abstract
A printed circuit board is configured as a daughterboard to include at least one lever pivotable between open and closed positions. The lever applies leverage to a card guide structure to selectively urge the daughterboard into or out of engagement with a connector of a motherboard. A manually operable pivotable latch member is mounted on the daughterboard for selectively retaining the lever(s) in a closed position. The latch member may be spring biased so that it maintains the lever(s) in the closed position and returns to a latch position after being manually pivoted to release the lever(s). The lever(s) may be spring biased toward the open position. An optical switch may be provided on the daughterboard to sense whether the lever is in a closed position, and to responsively interrupt power and/or bus signals to the daughterboard when the lever is not sensed in the closed position.
