A circuit breaker, comprising a housing (100), an input-side wiring terminal (111) and an output-side wiring terminal (112) which are positioned on the housing, and a moving contact (202) and a stationary contact (201) which are positioned in the housing. A passage (300) is arranged in the housing between two wiring terminals to be connected with a conductor (400), and the conductor connected with the two wiring terminals is arranged in the passage. Therefore, the present invention has the advantages of simple wire connection, good safety, space saving, beautiful appearance and clear and accurate indication of the switch state.

Embodiments described herein provide a low travel switch mechanism. The low travel switch mechanism may include a substrate, a dome coupled to the substrate, a keycap, and an integrated pivot component disposed between the keycap and the dome. The integrated pivot component may include a hinge assembly coupled to a light guide structure. The hinge assembly may secure to the substrate, via one or more hinge interconnects, joints, or interlock features to form a pivot point. When the keycap receives a keystroke, the integrated pivot component may be operative to pivot about the pivot point and contact the dome to cause a switching event or operation.

A key structure including a keycap, a bottom plate, a supporting element disposed on the bottom plate a backlight module, and a thin film circuit board is provided. The bottom plate includes a body and a plurality of protrusions, wherein the body has a plurality of openings, and the protrusions protrude from a first surface of the body and are disposed around the openings. At least two of the protrusions have different heights. The backlight module is disposed on a second surface of the body, wherein the first surface and the second surface are opposite surfaces. The thin film circuit board and the keycap are disposed on the first surface of the body, and the thin film circuit board is located between the keycap and the bottom plate, and the protrusions are located within an orthographic projection range of the keycap and do not contact the supporting element.

An input device configured to communicate with a computing device includes at least one keycap, a support mechanism operably connected to the keycap and configured to move the keycap from a first position to a second position, a feature plate operably connected to the support mechanism, and a sensing member. The sensing member is configured to detect at least one of a change of position of the at least one keycap, a speed of the at least one keycap, an amount of force applied to the at least one keycap, or a location of a finger. The sensing member may be a capacitive sensor. In some embodiments, the input device may not include the support mechanism and the sensing member may be configured to detect the location of a finger regardless whether or not the keycap moves.

A keyswitch structure includes a baseplate having a switch opening, a keycap movably disposed above the baseplate, a circuit board disposed on the baseplate, the circuit board having a through hole, and a mechanical switch disposed below the keycap, the mechanical switch extending through the through hole to be partially received in the switch opening and electrically coupled to the circuit board, wherein when the keycap moves toward the baseplate, the keycap triggers the mechanical switch.

The present invention relates to an enclosed type electromagnetic switch having a status indication function, and more particularly, to and enclosed-type electromagnetic switch having a status indication function that can show the electromagnetic switch's status on an enclosure.

A push-button switch (1) is arranged such that, once a user presses an operation button (8), a switch body (20) performs an operation, and light from an LED (21) passes through a transmission plate (70) and then illuminates the operation button (8). A structure (700) is provided on a lower surface (70b) of the transmission plate (70) to refract the light from the LED (21) so that the refracted light is reflected within the transmission plate (70) and then guided to an upper circumferential wall (71) of the transmission plate (70).

An operating panel device includes an operating ring, and a display device which is disposed to face a back surface of the operating ring. The display device includes a first portion, a second portion, and a third portion. The first portion is located inside the operating ring, and the second portion is located outside the operating ring. The third portion connects the first portion and the second portion. A display of the first portion changes in conjunction with a rotational operation applied to the operating ring.

A light-emitting keyboard includes a membrane circuit board including a lower layer, an upper layer and a light-guiding spacer layer arranged between lower layer, an upper layer and defining therein a tapered through hole, a substrate holding membrane circuit board, a key assembly including key cap, a linkage coupled between key cap and substrate and an elastic element supported between key cap and membrane circuit board, and a light source for emitting light into the light-guiding spacer layer. The light-guiding spacer layer uses its thickness to isolate the lower layer and the upper layer and its tapered through hole to provide room for a triggering stroke for enabling the upper layer to electrically contact the lower layer second circuit in producing a corresponding switching signal each time the key assembly is pressed. Thus, the light-emitting keyboard achieves the characteristics of low profile, low manufacturing cost, and simple assembly process.

Information handling system keyboard illumination is provided with micro LEDs disposed below keyboard keys to direct illumination at each key individually. The micro LEDs may be integrated at a bottom surface of a support plate below a keyboard membrane, on top of the support plate within an opening of the membrane or in a spacer layer of the membrane between circuit layers. A diffuser disposed between the micro LED helps to diffuse illumination directed at the key for a more even icon illumination. The diffuser may be integrated with the membrane at an upper circuit layer or over a structure disposed over the micro LED.
