A capacitance type light-emitting switch and a light-emitting switch
element are provided that operate properly by preventing failure in entry
and for which a small number of parts are used. A light-emitting switch
61 has a light-emitting switch element 51 and a control element 31. A
light-emitting switch element 51 has a panel 2 made of transparent
materials, a decorated layer 3 arranged on at least one side of the
panel, a light guide plate 4 arranged on the back sides of the panel and
the decorated layer, a point light source 5 or a line light source
arranged on the side of the light guide plate, and a reflective layer 1
that is made of an opaque metal film of less than 1.OMEGA./cm.sup.2 of
surface resistance measured by the four-point probe array measurement
method, mounted on the back side of the light guide plate, and is formed
to have an electrode unit 1a and a conductive unit 1b connected to the
electrode unit. The control element 31, which is connected to the
electrode unit 1a through the conductive unit 1b, switches a
circuit/circuits for an external loading device, depending on the change
in the capacitance of the electrode unit.
