Abstract

Systems and methods are disclosed that enable spring loaded mechanical key switch assemblies having variable displacement sensing capabilities. In one example, the disclosed key switch assemblies may be implemented in a keyboard system and used for providing variable displacement output signals that may be processed by a controller for input to a host processing device of an information handling system, such as a desktop or notebook computer. In another example, the disclosed key switch assemblies may be configured to provide both a digital “make” connection signal and separate variable displacement output signal/s that may be processed for input to a host processing device of an information handling system.
