In one aspect, a switch assembly includes two or more switch modules of different types and comprising different switch module subassemblies. The switch assembly also includes a switch housing having two or more sets of features integrally molded or formed in an underside or interior surface of the switch housing. Each set of features corresponds to a respective one of the different switch module subassemblies and comprises alignment and support features for the respective switch module subassembly.

An improved switch-type key structure includes a support plate, a microswitch, a connection element, and a key cap. The microswitch is fixed onto the support plate and is electrically connected thereto. The connection element is movably disposed on the support plate. The connection element includes a balance portion and a support portion extending downward from the balance portion. The key cap is disposed on the balance portion. The connection element is disposed between the support plate and the key cap through the microswitch, a hook hole corresponding to the support portion is disposed on the support plate, a hook is disposed at a distal end of the support portion, and the hook passes through the hook hole to engage the connection element with the support plate. Accordingly, the key cap is stressed evenly, returns instantly after being depressed, and is prevented from vibrations/wobbles.

A key structure includes a circuit board, a housing, a first metallic element, a second metallic element, a keycap and a conductive strip. The conductive strip is disposed within the housing. The first metallic element and the second metallic element are electrically connected with the circuit board. The housing is disposed on the circuit board. The keycap is fixed on the housing. While the keycap is depressed, a first end of the conductive strip is pressed by the triggering part and the conductive strip is swung relative to the housing. Moreover, a second end of the conductive strip collides with the second metallic element. Consequently, the key structure is triggered. When the second end of the conductive strip collides with the second metallic element, a click sound is generated.

An aerosol-generating device is provided, including: a button with an outer side facing towards an outside of the device and an inner side facing towards an inside of the device, the button being configured to be pressed in a pressing direction; and at least one light source provided within the device, the button including a button main body and a button light guide embedded in the button main body, the button light guide including at least one light entry surface on the inner side of the button and a light emission surface on the outer side of the button, the at least one light source including a plurality of light sources, the at least one light entry surface including a plurality of light entry surfaces, and each of the plurality of light entry surfaces being configured to receive light from a corresponding one of the plurality of light sources.

The microswitch is fixed onto the support plate and is electrically connected thereto. The connection element is movably disposed on the support plate. The connection element includes a balance portion and a support portion extending downward from the balance portion. The key cap is disposed on the balance portion.

Accordingly, the key cap is stressed evenly, returns instantly after being depressed, and is prevented from vibrations/wobbles.

An aerosol-generating device is provided, including: a housing having an outer surface, an inner surface, and a through-hole connecting the outer surface and the inner surface; a button at least partially arranged in the through-hole, the button being configured to be pressed in a pressing direction; a switch; an actuator, in which pressing the button in the pressing direction operates the switch via the actuator; and at least one guide pin extending into a corresponding at least one guide hole in the actuator, the actuator being configured to carry out a tilting motion when the button is pressed in the pressing direction. A method for actuating a switch of an aerosol-generating device is also provided.

An electronic device may have buttons, a display, and a vibrator unit. Buttons may be included in electronic devices such as glass buttons, metal buttons, buttons that are assembled on printed circuit boards, and buttons that are partly formed from antenna structures. Button coatings may be used to improve the sliding performance of metal-on-metal buttons. A layer of polymer may be interposed between a button plate and a housing structure. A glass button member may have an underside on which a layer of patterned ink is formed. Elastomeric members may be used to reduce button rattle. Portions of a button may be provided with conductive features that form portions of an antenna.

A trigger mechanism used in a power tool is disclosed to include a grip including a mounting chamber and two opposing first guide portions, and a tripper, which is mounted in the mounting chamber of the grip and movable by an external force along an axis direction relative to the grip and includes two opposing second guide portions respectively coupled to the first guide portions of the grip for enabling the trigger to move moved along the axis direction relative to the grip in a stable and smooth manner.

Dome switches can provide inconsistent positive tactile feedback, particularly when depressed around the edges of a corresponding push button as compared to depression at the middle of the push button. Various arrangements intended to render push buttons that incorporate one or more dome switches more consistent in providing positive tactile feedback, while maintaining a reasonable ease and cost of manufacturing, are discussed herein. A push button with consistent edge performance using a single dome switch incorporates a hinge arm that spans button posts. This reduces or eliminates rotation deflection of a button cap caused by the torsional forces on the push button created by depression forces applied by the user at an edge of the push button. As a result, the dome switch provides a predictable and consistent positive tactile feedback to the user similar to that achieved by a centrally applied depression force.

A waterproof button structure includes a housing, a button cap, a plurality of waterproof elements and a fastening member. The housing has a first surface and a second surface, and is formed with a pair of through holes and a groove. The button cap is capable of correspondingly moving a long a normal direction of the first surface of the housing, and includes a pair of button shafts respectively inserted in the pair of through holes. The waterproof elements are disposed between the button shafts and the through holes. The fastening member is assembled to the button shafts and is disposed correspondingly to the second surface. The fastening member includes a bent portion. The bent portion is disposed in protrusion towards the groove and includes a protrusion. When the button cap is pressed, the protrusion is abutted against a press switch.
