Abstract
An elastic apparatus used in a keyswitch key of a keyboard includes a bell-shaped shell having a top plate from which a receptacle extends upward for engaging with a keycap and from which an impacting portion projects downward and a base flange radially extends from a bottom peripheral edge of the bell-like shell for exerting a resilient force when the keycap is depressed to cause deformation of the elastic apparatus. A keyswitch key using the elastic apparatus is also disclosed for activating and deactivating a circuit unit which is positioned a predetermined distance below the impacting portion of the elastic device in an undepressed status and which is depressed by the impacting portion of the elastic device during depression of the keycap.
