Abstract: An electric capacitance-type touch switch, capable of reducing malfunction in switching operations and improving the degree of freedom in the visual design of switch, includes a detection circuit that can detect an electric capacitance change occurring when a human body approaches or contacts to an electrode. A sputter layer (i.e., a metallic thin film formed by sputtering) is provided on a surface of an upper lens (i.e., insulating base resin layer). The sputter layer can provide a beautiful metallic glossy appearance similar to a mirror surface. The sputter layer can be used as a panel surface providing a glossy appearance with iridescent or dichromatic effects obtainable from the hue of the base resin layer transmitted via the metallic layer. Furthermore, the sputter layer can be used as an electric capacitance detection electrode.

Abstract: A touch switch for controlling accessory equipment of a vehicle avoids a malfunction which is caused due to an environmental change such as a change in a state of air, arrival of unnecessary electromagnetic waves, or the like. Conductor plates 20-1 to 20-3 are disposed in an arrangement isolated from one another on a surface opposite to a sensor surface 16T of a touch plate 16 which is touched by a person's hand. The conductor plates 20-1 to 20-3 are each connected to a capacity measurement/control unit 34. The capacity measurement/control unit 34 determines as a judgment value D the absolute value of a value obtained by subtracting a minimum absolute value among changes ?C1 to ?C3 in electrostatic capacity from a maximum absolute value among the changes ?C1 to ?C3 in electrostatic capacity. The capacity measurement/control unit 34 controls a switch 28 according to the judgment value D.

Abstract: A light lens used for a car interior lighting device for transmitting light from a light source therethrough and illuminating the car interior is provided, and the light lens has a transparent light lens body, electrodes that are colored transparent conductive coating films for detecting the capacitance and located on a light source side of the light lens, and an insulative coating film that has almost the same color and transmission rate as the conductive coating films and is located on the periphery of the conductive coating films. With this configuration, the uniform light transmission rate is achieved over the light lens.

Abstract: A vehicle interior illumination apparatus includes a first type touch switch which turns illumination ON and OFF when a human body touches a surface of an illumination lens on a vehicle compartment side, and a second type touch switch which switches between linkage and non-linkage between ON and OFF of illumination and a state of a door when the human body moves on the surface of the illumination lens on the vehicle compartment side. The first type touch switch includes a first transparent electrode on a surface of the illumination lens on the light source side for detecting touch of the human body on the surface of the illumination lens on the vehicle compartment side, and the second type touch switch includes a plurality of second transparent electrodes on the surface of the illumination lens on the light source side for detecting movement of the human body on the surface of the illumination lens on the vehicle compartment side.

Abstract: A touch switch for controlling accessory equipment of a vehicle in such a manner that malfunctions caused by factors such as changes in atmospheric conditions, receipt of an electromagnetic impulse, or the like can be avoided.
