An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.

A device includes a housing; a substrate provided inside the housing; a light emitting object mounted on one side of the substrate; and an elastic sheet covering the one side of the substrate and the light emitting object, to guide light from the light emitting object. A through hole is formed in the housing corresponding to the one side of the substrate. The elastic sheet has a mirror part at a portion on the surface corresponding to the through hole, for totally reflecting light transmitting through an inside of the elastic sheet.

A touch-sensitive rotary control device with an illumination function includes a rotary encoder having a conductive outer casing and a rotatable shaft extending from it, the shaft operating as a light guide for a light source located in the rotary encoder, a conductive sleeve mechanically coupled to and surrounding the side of shaft, and electrically coupled to the conductive outer casing of the rotary encoder, so that touch-sensitivity is provided and light is allowed to exit the shaft and such that the device can be provided as a kit of parts or form part of a mixing console.

The invention relates to a system (10) for controlling industrial or all-terrain vehicle functions, which comprises data processing means (20), such as a computer, and a plurality of devices (10a-10g) for controlling industrial or all-terrain vehicle functions. The control devices are arranged in a network with the data processing means (20) according to a master-slave model, and each control device comprises at least one first control member (3a) sensitive to contact and connectors (2), a computing circuit (1) with at least one data processing unit (MC), a memory in which is stored a unique identifier associated with said control device, and at least one first control state visualization member (4a). The data processing means (20) are configured to transmit to each identified control device (10a-10g) a request to obtain a feedback of information from the associated processing unit.

A keycap, an illuminating keyswitch and a method for manufacturing the same are provided. The illuminating keyswitch comprises a base plate, a printed circuit board, a light emitting element, a keycap and a lifting support structure. The printed circuit board is disposed on the base plate. The light emitting element electrically is connected to the printed circuit board. The keycap is disposed on the light emitting element. The lifting support structure is disposed between the base plate and the keycap. The keycap comprises a first injection layer and a second injection layer. The second injection layer covers the first injection layer. The light emitting element is configured to correspond to the first injection layer or the second injection layer. The keyswitch of the present invention covers the first injection layer through the second injection layer, so that the surface of the key cap is flat, thereby facilitating subsequent processing.

An optic assembly for a light emitting diode mounted to a printed circuit board has a primary lens defined by a primary lens anterior surface and an opposed primary lens rear taper with a tip facing the light emitting diode. A secondary lens with a secondary lens anterior surface and an opposed secondary lens posterior surface faces the printed circuit board. The secondary lens defines a central cavity with the primary lens being disposed therein.

An electrical load controller includes an electrical switching device and an actuator assembly having at least one user actuator for use in turning power on and off to the load and for use in adjustably controlling the level of power to the load. A frame attached to the actuator includes an integrally formed backlightable indicator region having an outer continuous solid surface. Light from an illumination assembly related to the level of power to the load is directable onto a portion of an inner surface of the backlightable indicator region, transmittable through the backlightable region from the inner surface to the outer surface, emittable from a portion of the outer surface, and observable by the user.

In a first aspect of the present disclosure, a push switch includes a substrate including a first electrode and a second electrode that are arranged on an upper surface of the substrate; a resilient member arranged on the first electrode over the second electrode of the substrate; and a light-transmitting member including a crosslinked product of a chain olefin-cyclic olefin copolymer. The light-transmitting member covers the resilient member from above and includes an upper surface, a lower surface, a peripheral side surface between edges of the upper surface and edges of the lower surface of the light-transmitting member, and a periphery of the lower surface of the light-transmitting member. The periphery may be fixed on the substrate.

A control device includes a button assembly having one or more buttons and a button carrier that includes a plurality of resilient, independently deflectable spring arms. The control device may be configured as a wall-mounted keypad to control a load control device, or as a thermostat to control a temperature regulation appliance. The button carrier may be configured to prevent interference between the buttons during operation of the control device. The button assembly may be captured between a faceplate of the control device and a housing that is attached to a rear side of the faceplate. The control device may include one or more button retainers that are attached to the buttons and that are configured to align respective outer surfaces of the buttons relative to each other, and relative to the faceplate of the control device, when the buttons are in respective rest positions.

Embodiments are directed to an electronic device having an illuminated body that defines a virtual or dynamic trackpad. The electronic device includes a translucent layer defining a keyboard region and a dynamic input region along an external surface. A keyboard may be. positioned within the keyboard region and including a key surface and a switch element (e.g., to detect a keypress). A light control layer positioned below the translucent layer and within the dynamic input region may have a group of illuminable features. The electronic device may also include a group of light-emitting elements positioned below the optical diffuser. One or more of the light control layer or the group of light-emitting elements may be configured to illuminate the dynamic input region to display a visible boundary of an active input area. At least one of a size or a position of the visible boundary may be dynamically variable.
