It is a possibility. However on the last occasion before selecting cutout the trim switch was operating for 10 seconds continuously whilst the stick shaker was activated so I don't think it likely that the stick shaker can actually break the contact. We also have the Lion Air data and it doesn't speak to me of an issue with the stick shaker interfering with the operation of the electric trim switch.
