Abstract
A switch device is provided, in which a transparent key-top is arranged over a screen of a display unit so that information displayed on the screen of the display unit is seen through the key-top. The switch device is characterized by containing a shaft supporter provided in a space formed at both sides of the key-top for allowing the key-top to perform a seesaw-movement, wherein the space is formed by cutting off both sides of the key-top in an oblique direction so as to make an area of a face of the key-top larger than an area of a back of the key-top. Thus, the switch device achieves a seesaw-type key-top enabling a multiple display and improves visibility and operability for the seesaw-type key-top.
