  • Patent number: 6555774
    Abstract: A lever keyswitch for use primarily in electronic devices such as keyboards, mice, gaming devices, and the like includes a button portion secured to a base portion with a lever assembly that permits the button portion to move substantially linearly within its housing. Preferably, the lever assembly includes an elongate, resilient, U-shaped, lever extending from a base portion and an elongate, resilient, offset member extending from the center of the U-shaped lever to a button portion, which is encircled by the U-shaped lever. The lever and offset member work together to define a synthetic four-bar linkage, thereby allowing the button portion to move essentially linearly. More preferably, several keyswitches are integrally molded to a common base portion, forming a monolithic structure that may be quickly and easily manufactured and installed in the electronic device.
