What is presented is a key module for a keyboard. The key module comprises a key tappet. The key module also comprises a module housing. The module housing is formed to movably accommodate the key tappet, in order to enable a translational actuation movement of the key tappet between a rest position and in an actuated position relative to the module housing. The key module further comprises a trigger element for triggering an actuation signal of the key module in response to the actuation movement. The trigger element is attached to the key tappet. The trigger element is a contactor for electrically shorting contact pads of a circuit substrate of the keyboard. The trigger element comprises more than two elastically deformable contact fingers for contacting the contact pads after different pre-travel paths in the course of the actuation movement.

The invention relates to a switching-operation arrangement for a motor vehicle, having a movable actuating surface. The actuating surface has an extent along a first axis and a second axis, which are located perpendicularly to one another. The actuating surface interacts with a displacement means such that the actuating surface can be moved linearly, in the direction of a third axis (z), by at least one distance from a starting position into an actuating position, the third axis (z) being located perpendicularly to the first and second axes. The actuating position is in the form of a switching position and acts with switching action on a switching element or a sensor. The displacement means includes a guide means for guiding the actuating surface along the first axis and at least one braced-in elastic element for guiding the actuating surface along the second axis.

The present invention relates to a keyboard switch including a base, a supporting member, a spring, a button and an upper cover. The supporting member includes a first plate connected to the base to seal the opening, a tube extending substantially perpendicularly from a surface of the first plate, and a plurality of blocks extending substantially perpendicularly from the first plate and configured around the tube. There is a gap between the tube and the plurality of blocks. The base and the supporting member may be made of different materials and colors from the base, so that the supporting member may have a good light-shielding performance and durability; and the base may be made of a collocation of different materials and colors, and has a wide design space.

A user interface for a home appliance comprises a circuit board having at least one mechanically actuated switch having a first area. The user interface further comprises an input interface having at least one button defining a second area, greater than the first area, and having an actuator corresponding to the switch. The button is coupled to at least one of the circuit board or the input interface for relative movement between an actuation position, where the actuator actuates the switch, and a non-actuation position, where the actuator does not actuate the switch.

The disclosure provides a keyboard including a bottom plate, a key unit and a shielding layer. The bottom plate includes a through hole. The key unit is disposed on the bottom plate. The shielding layer covering a portion of the bottom plate includes a main part and an extension part extending from the main part toward the through hole. The shielding layer is provided with a black surface, and an orthographic projection of the key unit on the shielding layer overlaps the black surface.

A key module includes a base plate, a circuit layer and a lifting mechanism. The circuit layer is disposed on the base plate. The lifting mechanism is pivotally connected with the base plate relative to the circuit layer, and the lifting mechanism has an abutment element. The abutment element could interfere with the circuit layer to reduce the noise generated by the key module during operation.

A keyswitch structure includes a keycap, a base, and two supports pivotally connected to each other relative to a rotation axis and connected to and between the keycap and the base. One of the supports includes a first shaft recess, a first shaft portion, and a division slot formed therebetween; the other support includes a second shaft recess, a second shaft portion, and a division wall therebetween. The two supports are pivotally connected relative to the rotation axis by the first shaft portion and the second shaft portion rotatably disposed in the first shaft recess and the second shaft recess respectively. Therein, the division wall is inserted into the division slot. The keycap can move up and down relative to the base through the two supports.
