Disclosed herein is an oven including a display module. The oven includes a main body and a display module pivotably installed on the main body, wherein the display module includes a fixed module fixedly coupled to the main body, a moving module pivotably coupled to the fixed module and including a display panel provided to be manipulated by a user, a driving module and disposed on the fixed module and configured to generate a driving force such that the moving module is pivoted, and a detection module including a press pin configured to detect a position of the moving module depending on whether or not the press pin is pressurized.

A switch includes a base, a fixed contact member having fixed contact, and a movable contact member having a movable contact. The movable contact member moves in a first direction to bring the movable contact into contact with the fixed contact, and moves in a second direction opposite to the first direction to separate the movable contact from the fixed contact. The switch further includes a cover, an elastic body that energizes the movable contact member in the second direction, and an operation body configured to move the movable contact member sequentially to a first position, a second position, and a third position.

A switch mechanism includes a housing with a fenestration, a switch element held in the housing, and a first tab and a second tab each being pivotally attached to an opposite lateral edge of the fenestration. The tabs are constrained to rotational movement relative to the housing so that contact with the first tab or the second tab causes the respective tab to rotate to actuate the switch element.

A switch includes a housing, a switching mechanism housed in the housing and configured to switch a state of connection between at least two terminals exposed out of the housing by using a common contact and two switching contacts, and an electronic component that is disposed in the housing and electrically connects the terminals to each other. The switching mechanism includes a first metal plate that is connected to a first contact, which is one of the common contact and the two switching contacts, and includes a first exposed part to which a first electrode of the electronic component is soldered by laser irradiation, and a second metal plate that is connected to a second contact, which is another one of the common contact and the two switching contacts, and includes a second exposed part to which a second electrode of the electronic component is soldered by laser irradiation.

Keyboards are disclosed that are retractable. Movable magnetic or mechanical linkage elements are configured to reposition keycaps and stabilizers between different relative positions. Structures in a movable layer can act on the keycaps or stabilizers to move the keycaps and stabilizers into a retracted position for storage and for saving space in an electronic device. The stabilizers can be scissor mechanisms, butterfly mechanisms, and similar devices. The movable layer can be moved in response to rotation of a hinge or other mechanical element in the electronic device.

The present invention relates to a safety belt buckle, and more specifically, to a safety belt buckle which can stably detect whether a driver's safety belt is fastened even when foreign materials or water is introduced into the buckle in the case of being fastened with a tongue of a safety belt. In the safety belt buckle according to the present invention, a switch that detects whether a tongue of a safety belt is fastened is blocked from coming into direct contact with water or foreign materials, which are introduced from the outside, so as to stably detect fastening or unfastening of the tongue of the safety belt, and thus the safety belt buckle can be stably operated even when mounted in a seat exposed to the outside such as a seat of a forklift or a tractor.

A keyboard device includes a substrate, a keycap, a first connection member, and a first elastic arm structure. The substrate has a top surface, and the top surface has an assembling region. The keycap is disposed above the assembling region, and the keycap has a bottom surface facing the assembling region. The first connection member is connected between the keycap and the assembling region, the first connection member includes a first assembly side and a second assembly side opposite to the first assembly side, the first assembly side is pivotally connected to the bottom surface of the keycap, and the second assembly side is pivotally connected to the substrate. The first elastic arm structure includes a connection end and a free end opposite to the connection end, the connection end is connected to the first assembly side, and the free end abuts against the bottom surface of the keycap.

A switching device includes a switch and an actuating element. The actuating element for a switch includes a U-shaped actuating section. The actuating section includes two different arms with different lengths. The long arm is configured to transfer force to a button of the switch and a free end of the long arm is configured for holding the actuating element. The short arm is configured for the force input and is arranged aligned obliquely to the long arm.

A switch is provided with: a base; a fixed contact member that has a fixed contact; a movable contact member that has a movable contact, moves in a first direction to bring the movable contact into contact with the fixed contact, and moves in a second direction opposite to the first direction to separate the movable contact from the fixed contact; an elastic body that energizes the movable contact member in the second direction; and a cover that covers the fixed contact member and the movable contact member. An operation body is configured to move the movable contact member sequentially to a first position to which the movable contact member is moved from an initial position in the first direction to bring the contacts into contact with each other, a second position to which the movable contact member is moved from the first position in the second direction while the contacts are kept in contact, and a third position at which the movable contact member is moved again in the first direction from the second position, the third position located between the first position and the second position.

Adjustable add-on apparatuses for switches and associated methods are provided. In some embodiments, a float can actuate a first arm of the apparatus in response to a fluid level. The first arm can then actuate a second arm of the apparatus and, in turn, the second arm can open or close a switch, such as a micro switch. In some embodiments, the switch can be opened or closed through a lever and plunger assembly. Further, in some embodiments, apparatus can include a biasing means to bias the second arm into a first or second position without allowing it to rest in between the positions. Such apparatuses can include a micro switch or be retrofit to one. Methods of opening and closing a micro switch are also provided.
