Abstract

The upgraded long-stroke keyboard, particularly of the panel keyboard type or the like, comprises a surface plate having at least one opening in which is fitted at least one key sliding between an idle configuration, in which the key is substantially raised, and a keying configuration, in which the key is pressed to operate a corresponding underlying actuator, and elastic means operating in contrast to the sliding of the key from the idle configuration to the keying configuration, comprising at least one lamina spring which has at least one first end associated with the surface plate and a second end associated with the key and which yields by bending in the direction of sliding of the key from the idle configuration to the keying configuration.
