A light pipe structure includes a light guide pillar and a light shade tube. The light guide pillar, which is composed of a transparent material, is used for transmitting light. The light guide pillar includes a cylinder hole disposed in a terminal of the light guide pillar. The light shade tube, which is composed of a non-transparent material, is a hollow cylinder capable of being inserted in the cylinder hole. The hollow cylinder of the light shade tube has a shrinking structure.

A button structure applied in an electronic device includes an up-cover having a pressing portion including a button base and a center column portion disposed on the button base, wherein the center column portion has a first limitation portion, the first limitation portion includes a first tilt side surface; and a second limitation portion disposed on the up-cover, wherein the second limitation portion forms a hole and includes a second tilt side surface surrounding the hole. The present invention utilizes the limitation portion of pressing portion and the limitation portion of the up-cover to limit the range of recovering displacement of the pressing portion.

A voltage converter for determining whether input power is DC power or AC power includes a power input terminal, an AC to DC converter, a switch and a DC detector. The AC to DC converter converts AC power into a DC output voltage when the input power is AC power. The AC to DC converter includes a brown-out detector, for disabling the AC to DC converter when a voltage of the input power is smaller than a predefined voltage. The switch passes DC power when the input power is DC power. The DC detector determines that the input power is DC power and turns on the switch when the voltage of the input power is within a predefined voltage range, and determines that the input power is AC power and turns off the switch when the voltage of the input power is not within the predefined voltage range.

An electronic apparatus for processing a network communication operation includes a covering module including a lighting unit and at least one input unit; a base module including a heat-dissipation unit; a plurality of vertical electronic modules; a frame module including a plurality of connecting units for connecting the covering module and the base module to form a trapezoid column body, and the plurality of vertical electronic modules disposed to an edge of the trapezoid column body to form a column-shape wind channel; and a housing configured to cover the column-shape wind channel for protecting the plurality of vertical electronic modules.

An operation device driven by an internal battery includes: a casing; an operation element; a mechanical switch; a pressing part; and a support part. The operation element is located on a plane continuing from a front surface of the casing. The mechanical switch is disposed in the casing such that a distance between the mechanical switch and the operation element is fixed. The mechanical switch has a flexible region located to oppose to a rear surface of the casing. The pressing part is located between the mechanical switch and an attachment surface, and presses the flexible region from a side opposite from the operation element. The support part supports the casing such that a distance between the operation element and the attachment surface is changeable.

A frame module for an electronic device includes a plurality of brackets and a shield element. A connector for transmitting a radio-frequency signal is formed between two of the plurality of brackets. The shield element is fixed with the two of the plurality of brackets via riveting, wherein a hole is formed in the shield element, and the connector is placed in the hole to fix the connector after the shield element is fixed with the two of the plurality of brackets via riveting.

One embodiment of the disclosure includes an input module. The input module includes a switch, a rotatable and translatable input member operably connected to the switch and configured to actuate the switch, and an electrical contact operably connected to the switch and in electrical communication with the input member. During operation, the electrical connection between the input member and the electrical contact is maintained during translation and rotation of the input member. The input module may be used with a variety of electronic devices and can be used by a user to provide input to those devices.

An electrical contact assembly includes a first electrical contact having a first mating element, and a second electrical contact having a second mating element. The first and second electrical contacts being configured to mate together at the first and second mating elements such that the first and second mating elements engage each other at a contact interface. A distribution of contact pressure across the contact interface at least partially coincides with a distribution of electrical current flow across the contact interface.

An illuminated metal keycap having a legend diffuser material that may diffuse light through a legend opened in a background layer. The background layer may be opaque and the legend may be transparent. The metal keycap is adhered to a scissor mechanism positioned above electrical switch circuitry. Included within, below, or adjacent to the scissor mechanism may be one or more light sources positioned to emit light through the metal keycap, around the perimeter of the metal keycap, and/or through the background layer.
