Patent ID: 7671289

Claim:
A capacitance type light-emitting switch comprising: a light-emitting switch element comprising a panel made of transparent materials, a decorated layer arranged on at least one side of said panel, a light guide plate arranged on back sides of said panel and said decorated layer, a point light source or a line light source arranged on a side of said light guide plate, and a reflective layer that is made of an opaque metal film of less than 1Ω/cm 2 of surface resistance measured by a four-point probe array measurement method, mounted on the back side of said light guide plate, and is formed to have an electrode unit and a conductive unit connected to said electrode unit; and a control element that is connected to said electrode unit through said conductive unit, being capable of switching a circuit for an external loading device, depending on a change in the capacitance of said electrode unit.
