A second supported portion is supported in a second area by an electronic board. The second area is adjacent to one side of the electronic component. The push-in type switch is present in a first area which is adjacent to another side of the electronic component that is opposite to the one side. An elastic portion connects a portion including the second supported portion to a portion including the push button portion and the first supported portion. A plurality of guided portions are restricted by a plurality of guide projection portions projecting from an exterior member, from being displaced in a direction intersecting a depth direction. The plurality of guide projection portions are provided in the first area and the second area.

A keyboard device includes plural key structures, an electronic paper display element and an illumination module. The electronic paper display element is disposed under the plural key structures. The plural key symbols corresponding to the plural key structures are displayed on the electronic paper display element. The illumination module is disposed over the electronic paper display element to provide a light beam to the electronic paper display element. Consequently, the plural key symbols are illuminated.

The disclosure provides a button. The button includes at least one guiding component and a main body. The main body has at least one guiding surface. The guiding surface of the main body is slidably connected to the guiding component so as to allow the guiding component to guide the main body to move. In addition, the disclosure also provides a switch assembly and a computer host that have the button.

The invention relates to the field of switches, and particularly provides a switch for a vehicle and a vehicle. The invention aims to solve the problems of switch zero drift and shaking caused by the existence of a dimensional deviation of a switch of an existing vehicle. To this end, the switch according to the invention comprises a pressing rocking bar, a first push rod, a second push rod, a first elastic member, a second elastic member, a first limiting body, a second limiting body, and a housing, wherein the pressing rocking bar is pivotally connected to the housing; the first push rod and the second push rod respectively run through the first limiting body and the second limiting body and abut against bottoms of a first end and a second end of the pressing rocking bar, and the second push rod abuts against the second limiting body; and the first elastic member and the second elastic member are fixedly arranged and respectively connected to bottoms of the first push rod and the second push rod, torque of the second push rod acting on the second end is greater than torque of the first push rod acting on the first end, and a moving gap is reserved between the first limiting body and the first push rod in a pressing direction of the first push rod. Switch shaking is prevented and switch position accuracy is ensured.

A key inputting apparatus includes: a substrate provided with a switch; a key having a depression surface and a back surface on an opposite side to the depression surface, and a contacting section projecting from the back surface in a first direction from the depression surface toward the back surface; a panel having an opening in which the key is arranged; a first plate arranged between the substrate and the key in the opening of the panel; a second plate supported by the first plate between the key and the first plate; and a third plate arranged between the first plate and the substrate. The first to third plates are formed with first to third through portions, respectively, through each of which the contacting section is passable. The second plate is formed with a leaf spring section urging the key in a second direction opposite to the first direction.

A power supply includes a main body having a coupling face and a handlebar. The coupling face includes a first end and a second end forming a power socket. The handlebar includes a first beam coupled to the first end and a second beam. The first beam extends a tab outwardly. The handlebar defines a window configured to expose the power socket. The handlebar is transitionable between: (i) a first configuration in which the second beam couples the second end, the window corresponds and exposes the power socket, the tab extends toward a first direction, and (ii) a second configuration in which the second beam is remote from the second end, the window is remote from the power socket, and the tab extends toward a second direction different from the first direction. A method for removing the power supply from a case of an electronic device is also provided.

A keyboard device includes plural key structures, an electronic paper display element and an illumination module. The electronic paper display element is disposed under the plural key structures. The plural key symbols corresponding to the plural key structures are displayed on the electronic paper display element. The illumination module is disposed over the electronic paper display element to provide a light beam to the electronic paper display element. Consequently, the plural key symbols are illuminated.

According to various embodiments, there is provided a key assembly including a housing including a sliding groove on an inner surface of the housing and further including a contact surface above the sliding groove; a plunger at least partially fitted into the housing, the plunger including a protrusion; a sound producing member provided at least partially in the sliding groove, the sound producing member configured to produce sound by impacting the contact surface; wherein the sound producing member includes a connecting portion obliquely extending to an abutting portion, the abutting portion arranged below the protrusion; wherein the plunger is displaceable downwards to deform the connecting portion using the protrusion, the deformed connecting portion being reboundable to cause impact the sound producing member to impact the contact surface.

A keyboard switch includes a base, a static contact, a movable contact, an upper cover, a button and a reset spring; the upper cover is buckled to the base; one end of the button is install on the base and the other end passes through the upper cover; the upper and lower ends of the reset spring respectively abut against the button and the base; at least two balance bars for preventing the button from tilting; at least four rotating grooves and guiding grooves for installing the balancing levers are further included; the body of the balance levers are rotatablely rotatably embedded in the rotation grooves, and both ends of the balancing lever are rotatablely rotatably embedded in the corresponding guiding grooves and move back and forth along the guiding grooves.
