CAPACITANCE TYPE LIGHT-EMITTING SWITCH AND LIGHT-EMITTING SWITCH ELEMENT USED FOR SUCH CAPACITANCE TYPE LIGHT-EMITTING SWITCH |
摘要 |
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©/cm 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. |
