Pressing intrusion-detection module for a computing storage device
A computing system includes a drawer configured to receive a plurality of computing storage devices. The drawer is movable between an open position and a plurality of closed positions. A printed circuit board (PCB) is mounted within the drawer in electronic communication with the plurality of computing devices. An intrusion-detection switch is attached to the PCB and is configured to detect movement of the drawer between the open position and the closed positions. A pressing module is attached to the movable drawer for extending an operating range of the intrusion-detection switch.
