A flat piece or panel forming the back support or cover of something, such as a switch plate, mechanical device, or piece of equipment.
From back (Old English bæc, rear) + plate (from Old Dutch plaat, meaning flat sheet), literally 'a flat piece for the back.'
Backplates are the unsung heroes of design—they're what you don't see, but they hold everything together structurally while protecting the mechanisms behind the scenes.
