Seems the 737 assertions may be relying in the switch and its actuation functions interfacing with the flash memory; and possibly the integrity verification of external secondary storage, this may be taking us deeper into damages... I always said that rocker-switch was a jewel imo.

Abstract
A solid state digital hand held recording device having a multifunctional switch assembly.

9. A device for enabling the testing of memory integrity in a removable flash memory recording medium and the marking of defective memory such that voice messages are only recorded to segments of flash memory capable of storing electrical signals, said device comprising:

a solid state digital hand held recording device having a multifunctional switch assembly and a record switch assembly, the flash memory digital recording medium including a region forming a continuity of pre-recorded messages, a printed circuit board including a microcontroller electrically coupled to the switch assemblies and operable to (1) control the processing of sound into electrical signals, (2) store said electrical signals on the recording medium, and (3) play said sounds stored in the flash memory digital recording medium; and

memory integrity verification means for ascertaining whether the flash memory digital recording medium can record voice messages to said memory with no manual involvement of the user other than inserting the removable flash memory digital recording medium into a plug assembly in said recording device.
