A key structure includes a base and a linkage mechanism. The linkage mechanism includes a plurality of linking members movably connected to each other. The plurality of linking members includes at least two linking members rotatably positioned on the base, respectively. When a pressing force is applied to the linkage mechanism, the plurality of linking members move associated with each other to restrict a rotation range of the plurality of linking members with respect to the base.

The present inventors have recognized that an electrical switch for opening doors in buildings, calling elevators, and the like can be improved to require less physical contact, larger activation area, and multiple activation methods, with increased reliability, by utilizing a piezoelectric sensor specifically arranged between rigid, parallel mounting plates in which one of the plates (an inner plate) is rigidly fixed to prevent movement while the other plate (an outer plate) is accessible for receiving physical contact. By rigidly fixing the inner plate, such as by mounting to a wall or bollard, the sensor can react with sensitivity upon an application of less pressure on the outer plate. Such pressure compresses the sensor between the plates to produce an electrical signal. A controller receiving the signal can, in turn, execute to open a door, call an elevator and/or activate a light or sound to provide feedback.

A switch panel for an aircraft includes a cover and aback plate. A distance from the cover to the back plate is a thickness of the switch panel. In some cases, the thickness is less than about 9.525 mm. A button assembly for a switch panel for an aircraft includes a button base, a button retainer, and a lens. The button base includes a bottom end, a base side, and a transition portion between the bottom end and the base side. In certain cases, the transition portion of the button base is beveled or radiused with a sloped or concave shape.

A detachable pushbutton structure includes a case seat which is formed with an internal receiving space for receiving a base seat and a linking member. The base seat has multiple contact legs. The linking member is drivable to control the respective contact legs to form different conducting states. A support seat connected with the linking member and has an internal penetrating hole. A light-emitting member is received in the penetrating hole and connected with the base seat. A connected section is disposed on an outer side of the support seat. A cap assembly can be tightly capped on the penetrating hole of the support seat. A pushbutton is capped on the cap assembly and has a connection section detachably connected with the connected section. A protective ring securely connected between an inner circumference of the receiving space and an outer circumference of the support seat.

An illuminated keyswitch structure with an illuminating module includes a base plate, a drive circuit board under the base plate, a spacer between the drive circuit board and the base plate, and a light-emitting part on the circuit board. The spacer has a through hole communicating with an opening of the base plate in a vertical direction. The light-emitting part is located in the through hole, and falls within a projection of the opening in the vertical direction. The light-emitting part has a top surface that is lower than or equal to a bottom surface of the base plate in the vertical direction. The structure of the illuminated keyswitch structure around the light-emitting part can keep flat by the spacer. The spacer can prevent the light-emitting part from structurally entering the opening, avoiding structural interference between the light-emitting part and other components above the base plate.

A compact automobile start switch with antenna including a button, a push switch assembly and an antenna assembly module is disclosed. The antenna assembly module is provided with an accommodating cavity in which the push switch assembly is arranged. The antenna assembly module includes an antenna module body, an antenna coil and a connector terminal. The antenna module body is provided with a winding area in which the antenna coil is arranged and a connector matching portion in which the antenna connector terminal is arranged. The antenna connector terminal comprises a connecting section, a fixing section and a terminal welding section and the antenna coil is directly connected with the terminal welding portion by a wire. The antenna coil is directly connected to the antenna connector terminal through the wire outside the antenna module body. The process of connecting the antenna module to the circuit of the PCBA is eliminated.

A compact switch mechanism operating a contactor array and having a lighted display.

The present invention provides a vehicle push switch unit (10) comprising: a unit housing (100) mounted in a vehicle; and a unit switch part (300) including a unit switch moving block (320) movably mounted in the unit housing (100), and a unit switch (310) for changing a switching operation signal according to the movement of the unit switch moving block (320), wherein the unit switch moving block (320) and the unit housing (100) have unit stopper parts (500), and at least a portion of the unit stopper part (500) is injection-molded.

A printer includes: a body defining a media enclosure configured to receive a media supply; an indicator assembly supported by an outer wall of the body, the indicator assembly including a plurality of substantially contiguous illumination surfaces illuminated by respective ones of a set of lights supported within the body; a controller supported by the body, the controller configured to: (i) obtain an operational status of the printer, (ii) retrieve, from a mapping repository, a set of notification control parameters corresponding to the operational status, and (iii) control the set of lights according to the notification control parameters.

A switch with backlight device, adapted to switch on internal or external lights and to be used for electrical outlets, heat regulators or for opening or closing doors and gates, includes lighting bodies and transparent sides configured to allow the passage of the light emitted by the lighting bodies toward the outside. The switch with backlight device is also provided with a wireless remote connection system suitable for the wireless remote connection of a mobile device, such as a mobile phone or a tablet, which is configured to transmit commands for switching on the backlight of the switch.
