The invention relates to a step switch unit (2) for sequentially switching currents, comprising at least two switching contacts (3) and a switching unit (4) with actuators (5) which are arranged on the switching unit (4) above the switching contacts (3) at different distances from them, wherein the switching contacts (3) and the switching unit (4) are arranged relative to each other such that when pressure is applied to the switching unit (4) in the direction of the switching contacts (3), the actuators (5) are pressed onto it and different actuators (5) touch the switching contacts (3) at different pressure forces. wherein the switching unit (4) extends at least partially over the switching contacts (3) and has a planar reset area (R) made of an elastic plastic material which exerts a force on the actuators (5) directed away from the switching contacts (3). Furthermore, the invention comprises an operating device (1) and a medical device.

Disclosed herein is a novel backlit surface mounted switch for an illuminated application. The backlit switch does not have an integrated LED or other type of light but is designed to be positioned over a light source mounted on or under a PCB, such that the light source shows through the actuator of the switch when illuminated.

The invention relates to a control module (10) of an electronic device characterized in that it comprises a push button (11) including a striking element (111), a switch (12) adapted to occupy a connected state and a rest state, said striking element (111) being configured to drive the switch (12) into the connected state or into the rest state when the push button (11) is activated, the control module further comprising a damper (116) configured to absorb, by elastically deforming, a portion of the forces involved when the striking element (111) drives the switch (12) into the connected state or into the rest state, at least when said forces are greater than a predetermined threshold.

A switch includes a housing and a metal terminal that is insert-molded into the housing. The metal terminal includes a contact portion provided on a first side of the metal terminal, an external connection portion provided on a second side of the metal terminal, and an embedded portion provided between the contact portion and the external connection portion and embedded in the housing. In the embedded portion, groove portions are formed in a front surface of the metal terminal and a rear surface of the metal terminal, the groove portions in the front surface being formed at positions different from the groove portions in the rear surface. The groove portions extend in a widthwise direction that is a direction intersecting an extending direction of the embedded portion.

Disclosed herein is a novel backlit surface mounted switch for an illuminated application. The backlit switch does not have an integrated LED or other type of light but is designed to be positioned over a light source mounted on or under a PCB, such that the light source shows through the actuator of the switch when illuminated.

Push buttons utilizing dome switches are often preloaded to take up any tolerances in the push button design causing a gap and provide consistent tactile feedback to a user. However, conventional push button preload techniques can be costly and difficult to consistently reproduce during push button manufacturing. The presently disclosed technology employs a new pre-load design without requiring pre-depression of the dome switch to close the gap, which permits a more forgiving tolerance to manufacturing variations.

A novel backlit surface mount switch for light emitting applications is disclosed. The backlight switch does not have an integrated LED or other type of lamp, but is designed to be positioned above a light source mounted on or below the PCB such that the light source is displayed by an actuator of the switch when illuminating.

An illuminated keyswitch includes a base plate, a keycap, a light source disposed on the base plate, and a light-guiding device. The keycap is connected above the base plate with upward and downward movement. The light-guiding device includes an actuating portion and a light-entry portion connecting the actuating portion. The light-entry portion has a first reflective surface, and is positioned above the base plate such that the first reflective surface is located above the light source. The actuating portion has a second reflective surface far away from the first reflective surface, and is positioned between a bottom surface of the keycap and a switch contact. A light emitted by the light source is directed upward into the light-guiding device, reflected by the first reflective surface and guided by the light-guiding device out of a front face of the actuating portion to uniformly illuminate a translucent region of the keycap.

A backlight module includes a circuit board, a light emitting unit, a reflection plate, a light guide plate, and a light shielding sheet. The light emitting unit is disposed on the circuit board. The reflection plate is disposed above the circuit board. The light guide plate is disposed above the reflection plate and includes a single-key light guide area. The single-key light guide area includes a receiving hole and a light blocking structure. The receiving hole penetrates the single-key light guide area and receives the light emitting unit. The light blocking structure is arranged with the light emitting unit in a direction. The light shielding sheet is disposed above the light guide plate. Thus, the problem of uneven brightness of different areas of the key can be effectively solved.

The present disclosure relates to a component for the surface soldering installation on a circuit board, comprising: a basic body forming at least one locating surface provided for contact with a surface of the circuit board, or several locating points spanning a plane; two elastic brackets, which are formed on opposing sides of the basic body and respectively form one soldering surface for a solder connection with a positioning surface of the circuit board, wherein each of the two brackets has, in sequential arrangement over its course from the basic body to the soldering surface, a strip-shaped, flat, first portion and a strip-shaped, flat, second portion, wherein the main surfaces of the first portion are arranged at an angle to the main surfaces of the second portion; a use and an associated assembly.
