A backlight apparatus includes a light-guiding plate, a light-shielding membrane, a light-reflecting sheet, a plurality of first translucent glue bodies, and a plurality of second translucent glue bodies. The light-guiding plate has a plurality of through holes. Each of the first translucent glue bodies corresponds to one of the through holes. Each first translucent glue body is placed on a front surface of the light-guiding plate, and surrounds a respective circumference of the corresponding through hole to bond the light-shielding membrane thereabove and the light-guiding plate therebelow. Each first translucent glue body has a respective breach. Each of the second translucent glue bodies corresponds to one of the first translucent glue bodies, is placed via at least one portion thereof in the breach of the corresponding first translucent glue body, and bonds the light-shielding membrane thereabove and the light-guiding plate therebelow.

An autoclavable medical device is provided that includes a metal housing having an electrical conductor embedded in an inorganic fixing material. The conductor and fixing material define an electrical feedthrough that extends from an interior of the housing through at least a portion of the fixing material. The electrical feedthrough forms part of a sensor of an actuation means for the autoclavable medical device.

Provided are a switch module and a push switch that have a soft sensation when pressed. A push switch and a switch module have a substrate, a first fixed contact point disposed on the substrate surface, a second fixed contact point disposed around the first fixed contact point on the substrate surface, a convex dome-shaped upper spring disposed on the substrate surface so that an end part is in contact with the second fixed contact point, the upper spring being pressed so as to invert the dome shape and to establish conduction between the first fixed contact point and the second fixed contact point, and a lower spring disposed below the upper spring, the lower spring adjusting the operation load applied to the upper spring during inversion of the dome shape.

A wireless load control system is provided including one or more wireless switch components and one or more load controller components optionally in one-to-one, many-to-many, many-to-one, and one-to-many wireless communication with each other. A wirelessly-controlled load controller assembly includes an enclosure adapted to fit within a junction box, the enclosure comprising a projecting fitting adapted to fit through an aperture of the junction box to maintain the enclosure in fixed relation to the junction box. A control circuit in the enclosure is provided with an antenna that extends through an antenna port that is disposed within the fitting so that when the load controller is mounted in a junction box, the antenna extends through the aperture of the junction box.

Embodiments of the present invention provide switch cells that use a non-electrical tactile feedback pad to adjust the tactile feel of the included switches. As a non-limiting advantage, separating the tactile feedback pad from the electrical switching operation allows the electrical contacts to be configured for high-current applications while relying on the tactile feedback pad to define or “tune” the tactile feel of the switch cell. Moreover, the same switch cell design may be used to meet a variety of tactile feel requirements, simply by installing different tactile feedback pads. That is, the same switch cell can be reconfigured to have a different tactile response curve simply by changing out the tactile feedback pad(s) used in the switch cell, without affecting the electrical characteristics of the switch cell.

A key structure includes a membrane switch, a keycap and an elastic conduction element. The keycap is located over the membrane switch. The elastic conduction element is arranged between the keycap and the membrane switch. The elastic conduction element includes a supporting cover and a conduction post. The conduction post is connected with the supporting cover and disposed within an accommodation space of the supporting cover. The conduction post includes a first contacting part, a second contacting part and a concave part. While the keycap is moved downwardly relative to the membrane switch, the supporting cover is compressed by the keycap and the conduction post is correspondingly moved downwardly. Consequently, the first contacting part and the second contacting part are contacted with the membrane switch, and a suction force between the concave part and the membrane switch is generated.

A backlight apparatus, used in an illuminated keyboard, includes a light-guiding plate, a light-shielding membrane, a light-reflecting sheet, a plurality of first translucent glue bodies, and a plurality of second translucent glue bodies. The light-guiding plate has a plurality of through holes. Each of the first translucent glue bodies corresponds to one of the through holes. Each first translucent glue body is placed on a front surface of the light-guiding plate, and surrounds a respective circumference of the corresponding through hole to bond the light-shielding membrane thereabove and the light-guiding plate therebelow. Each first translucent glue body has a respective breach. Each of the second translucent glue bodies corresponds to one of the first translucent glue bodies, is placed via at least one portion thereof in the breach of the corresponding first translucent glue body, and bonds the light-shielding membrane thereabove and the light-guiding plate therebelow.

A key structure includes a casing, a covering member, a pressing element, a triggering post, a switch element. The casing has an opening. The opening is covered by the covering member. The pressing element is disposed within the opening and connected with the covering member. The pressing element includes a middle part and an extension part. The triggering post is installed on the middle part of the pressing element. The triggering post is extended in the direction toward the inner position of the casing. When an external force is applied to the middle part of the pressing element, the triggering post is moved toward the switch element to push the switch element. When the external force is applied to the extension part of the pressing element, the triggering post is correspondingly moved with the pressing element in an inclined manner to push the switch element.

A switch device includes a first rubber dome, a second rubber dome, and a slider disposed on the first rubber dome and the second rubber dome. The slider presses the upper surface of the first rubber dome, causing deformation of the first rubber dome when the slider is moved toward the first and second rubber domes, and presses the upper surface of the second rubber dome, causing deformation of the second rubber dome when the slider is further moved toward the first and second rubber domes in a state in which the first rubber dome is subjected to the deformation. A thick portion is formed on each side of the second rubber dome so as to increase the thickness on the each side of the second rubber dome. Each side of the second rubber dome is in a direction in which the first and second rubber domes are aligned.

An inspection station is capable of being used under harsh conditions. The inspection station includes switch elements to which the inspection station is responsive for generating a predetermined control signal in response to actuation of a switch element. A fluid tight sealing element isolates an interior of the inspection station from an outside of the inspection station, the sealing element including one or more flexible button areas at the locations of the switch elements to provide access from the outside of the inspection station to actuate the switch elements located in the interior of the sealing element.
