Abstract: A touch panel of the present invention is provided with a transparent substrate, sensor electrodes, terminals, conductive wires, and auxiliary wires. The sensor electrodes are made with transparent conductive members arranged and formed in a detection region on the substrate. The terminals are formed in a wiring region on the substrate and correspond to the respective sensor electrodes. The conductive wires are formed in the wiring region on the substrate, and electrically connect any of the sensor electrodes and the terminal corresponding to the sensor electrode. The auxiliary wires are formed in the wiring region on the substrate, and electrically connect any of the sensor electrodes and the terminal corresponding to the sensor electrode. The conductive wires are of a material having electrical resistivity lower than that of the auxiliary wires, and the auxiliary wires are of a material less prone to corrosion than that of the conductive wires.

Abstract: A push type switch which enables an operator to obtain an upscale impression when he operates the push type switch. A switch body 3 is rigidly fixed to a printed wiring board 5. A casing 7 having a plurality of guide grooves 71h is fixed to the printed wiring board 5. A plurality of rails 91a provided on a knob 9 capable of transmitting a pushing force to the switch body 3 are slidably inserted into the guide grooves 71h such that the knob 9 can slide on the casing 7. A grease is applied to the guide grooves 71h and the rails 91a. The viscosity of the grease is set to be within a range of 1000 to 2750 Pa.

Abstract: A first predetermined operation is performed when a contact detector detects contact with an operation knob. A time length of the contact thus detected by the contact detector is measured and it is determined whether the time length of the contact is longer or shorter than a predetermined value. When it is determined that the time length of the contact is longer or shorter than the predetermined value, a second predetermined operation is performed.

Abstract: A membrane switch which can be opened and closed with a small pushing load. A fixed contact point 4 is formed on one surface of a first sheet 3. Flexible movable contact points 7 opposed to the fixed contact point 4 via a space in a manner movable to and way from the fixed contact point 4 are formed on one surface of a second sheet 6, opposed to the one surface of the first sheet 3. Insulators are arranged on the flexible movable contact points at locations except for the locations of push portions of the flexible movable contact points 7.

Abstract: A pusher formed of a rubber material, a click plate, a membrane switch which serves as a second step switch, a reinforcing plate, a membrane sheet on which a plurality of first step switches are formed, a key operation base and a knob are sequentially assembled into a case. The knob includes a plurality of depressing pieces having on its internal surface a projection which moves into contact with each membrane switch and also includes a marginal portion which is supported by the top surface of the case. The knob is thin-walled except for the depressing piece, and the thin-walled portion comprises a thermoplastic elastomer or silicone rubber. The knob, the key operation base and the reinforcing plate are secured together. As the depressing piece is depressed, the thin-walled portion which is located therearound becomes flexed, whereby the membrane switch is depressed by the projection to turn the switch on.

Abstract: Outer ends of link members supported to a case and having their inner ends coupled to each other are coupled to a slider. A membrane sheet and a pusher are disposed one after the other on the slider, and a knob having molded therewith a surface sheet is fixed to the slider. On a bottom plate are mounted a tactile push-button switch and a light source. No matter which press area is depressed, the slider is uniformly translated by the link mechanism to actuate the push-button switch. The link mechanism, the slider, the membrane sheet except conductor portions, and the pusher are formed of a light transmitting material.

The switch comprises: a box-like operation knob; a square frame-shaped holder disposed in the inside of the operation knob; a case having an outer square tube-like member and an inner square tube-like member coaxially formed; and a base plate on which a light source and a plurality of switch elements are to be mounted. The operation knob is rotatably supported by the holder disposed in the inside of the operation knob, and the holder is rotatably supported by the inner square tube-like member of the case by a second axis for rotating movement orthogonal to the axis for rotating movement of the operation knob.
