A switch fastening structure for a keyboard is provided to radiate a light illuminated by a light emitting device from a key bottom plane to a key-top without an interruption of a base unit by changing a shape of a base unit. A switch fastening structure for a keyboard includes a base unit, a membrane switch unit(20), an elastic driving unit(22), a link unit, and a key-top(40). The base unit is arranged in a bottom plane of a key. The switch unit is installed on an upper plane of the base unit, and has a contact point unit. The elastic driving unit is installed on an upper part of the contact point unit of the membrane switch unit, and elastically changes and connects the contact point unit. The link unit has a first link and a second link. An end of the first link is rotatably fixed on a first hinge unit formed on an end of the base unit. An end of the second link is rotatably fixed on a second hinge unit formed on an opposite side to the first hinge unit of the base unit. The first and second links rotatably cross on a center. The other end of the first link is opposite to the other end of the second link. An aperture is formed on a center of the base unit. The first and second hinge units of the base unit are fixed on a circumference of the base unit.
