Abstract
A keyswitch assembly for constructing a computer keyboard consists of a cap for receiving a key-in force from a user, a link, a conductive rubber, a circuit membrane, a mounting block and a base plate. The base plate defines a number of recesses in one of which the mounting block is fittingly received. The mounting block is formed by plastic injection molding to integrally have mounting brackets and L-shaped protrusion which project through the circuit membrane to supportively engage with a lower portion of the link. An upper portion of the link engages with the cap. The conductive rubber is located on a corresponding switch of a circuit on the circuit membrane and has an upper portion extended through the link to engage with the cap. In an alternative embodiment, screws are used to fixedly connect the mounting block and the base plate together. In a further alternative embodiment, a heat melting operation is applied to a free end of a shaft of the mounting block extending through the base plate to fixedly connect the mounting block and the base plate together.
