  • Patent number: 11901137
    Abstract: A key module includes a keycap, an indicator light source, a first backlight source and a second backlight source. The keycap includes an indication area and a character area. The indicator light source is configured to emit an indicating light of a first color toward the indication area. The first backlight source is configured to emit a first backlight of the first color toward the character area. The second backlight source is configured to emit a second backlight of a second color toward the character area, wherein the second color is different from the first color. As a result, the key module could display the light of different colors based on different operations, thereby being distinguishable from the color of the light emitted by the adjacent key module.

    Abstract: A setting device includes a rotating actuator, a switch, an illuminated index display on which a value which is manually set at the rotating actuator is assigned to the rotating actuator and, by actuating the switch, the manual setting at the rotating actuator can be overridden. To improve the display of the setting device, a light device is provided in addition to the rotating actuator. The switch, aside from its actual switching function, is constructed for switching over between the illumination of the index display and the operation of the light device. The illumination of the index display is activated when the rotating actuator is a manual mode, and the light device is activated when a different mode is set by the actuation of the switch.

  • Patent number: 6628192
    Abstract: A push-pull circuit breaker is provided primarily for use in aircraft; wherein, the activation of the circuit breaker is made significantly more noticeable by the addition of a “flower” device. Specifically, as the center post of the circuit breaker deploys, “petals” at the periphery of the post expand outward. The petal expansion greatly enhances the visibility and thereby recognition of said circuit breaker deployment by flight crew or maintenance personnel. This design capitalizes on the safety and reliability of existent circuit breaker designs. Finally, the flower design incorporates only one part interlocked with the circuit breaker post to achieve the stated purpose.

  • Patent number: 5833350
    Abstract: A wall switch cover plate conceals an electrical circuit capable of sensing the field provided by the covered switch circuit. When power is lost at the switch circuit the electrical circuit senses the loss of power and activates one or more LEDs to provide emergency illumination. The electrical circuit is self contained and does not require stand-by energy so that the batteries are long lasting.

  • Patent number: 5713458
    Abstract: A manually operable "bubble" button for an amusement device, such as an arcade game, includes inner and outer nested, generally cup-shaped members formed of suitable plastic material. The inner member has an annular flange which seats on an annular shoulder of the outer member to limit the depth of insertion so that the concave wall portions of the members are spaced apart. Circumferentially spaced ribs on the inner member engage the outer member to center the members and a locating tab on the inner member seats in a recess in the outer member to ensure proper relative orientation of the members. An indicium is disposed between the inner and outer members, preferably being fixed to the inner member, at least the outer member being substantially transparent to visible light so that the indicium can be seen therethrough. The members are fixed together adjacent to their open ends.

  • Patent number: 5464955
    Abstract: A household appliance operated by electromechanical controls has a control console that contains a light source to project light onto selected portions of a plastic control console faceplate to illuminate data such as appliance functions and control settings. Data on the control console plastic faceplate can be illuminated upon the occurrance of a predetermined event and in different colors. Control knobs carry a plastic disk that has illuminated data, a clear selection window, and a translucent portion which aligns with illuminated data on the plastic control console faceplate.

  • Patent number: 5451732
    Abstract: The invention relates to a selection and/or adjustment button mounted on a front panel, the button being of the type constituted by a translucent body having a front face which is illuminated when the front face is illuminated from the inside. The button is provided with a non-translucent contrast piece that forms a reflective front surface that provides significant contrast relative to the front panel in full sunlight, and that delimits the outline of the front face of the button in front view. For example, the contrast piece may be constituted by a fillet or chamfer interconnecting two geometrically similar portions of the button body, whereby the contrast piece is visible only when the button is not pushed in.

  • Patent number: 5408060
    Abstract: An illuminated keyboard in which the keys are operable in at least two different modes. Each key is provided with symbols or areas of color which denote the different modes. The symbols or areas are selectively illuminated depending upon which mode is selected. Thus, in one mode, one area of the keys will be illuminated, while in another mode, another area of the keys will be illuminated. Thus, only the symbols or areas of color on denoting a selected mode are differentially visibly distinguishable by the user, assisting the user to press the correct key, in any selected mode.
