In a multistage pushbutton switch device, n pushbutton switches and at least one load absorption spring are movably arranged in between a pushbutton member and a reaction force wall in the same axial line, each of the n pushbutton switches is composed of an electrical switch member and a pressing member that operates the electrical switch member, and (n?1) that is one less than n, or more pushbutton switches is arranged with an intermediate spring member, when the pushbutton member is pressed and displaced, the n electrical switch members are sequentially turned on, the load absorption spring is arranged in at least one of between the pushbutton member and the pushbutton switch that is the nearest to the pushbutton member, between pushbutton switches that are adjacent, and between the reaction force wall and the pushbutton switch that is the nearest to the reaction force wall.

Provided is a switch that can be downsized. A switch is provided with a plunger, two upper torsion springs that bias the plunger in a returning direction, housing-side contacts, and plunger-side contacts. One of the upper torsion springs is arranged on one side of a plane that includes an axis passing through a central portion of the plunger, and that is perpendicular to perpendicular lines M connecting the plunger-side contacts and the axis, and the other one of the upper torsion springs is arranged on the other side of the plane.

Provided is a switch with excellent operability. A switch is provided with a plunger, a lower torsion spring in which a biasing direction changes according to the movement of the plunger. The lower torsion spring biases the plunger in a returning direction when the plunger is in a reference position, and biases the plunger in a direction different from the returning direction when the plunger is in an operation position.

This application relates to a dome switch assembly including a base plate that carries a first contact, and a flexible surface connected to the base plate, the flexible surface formed of a metal material in the shape of a dome. The assembly can include a second contact coupled to the flexible surface, and a sound-dampening pad coupled to the flexible surface and formed of a material having noise-dampening properties, wherein when at least a threshold amount pressure is applied to the flexible surface, the flexible surface changes from the dome shape to a collapsed shape allowing the first and second contact to touch, wherein the sound dampening pad absorbs at least some acoustic energy emitted by the touching of the first and second contacts.

An operation device (200) for remotely operating an X-ray imaging device (1) includes an operation unit (280), a grip detection unit (240), which determines whether an operation received by the operation unit (280) is a normal operation or an erroneous operation, and a control unit (230), which transmits an operation signal corresponding to the operation to the X-ray imaging device (1). The control unit (230) transmits the signal when the grip detection unit (240) determines that the operation is a normal operation. The operation device is prevented from causing an erroneous operation of its target device.

This application relates to a switch that can include multiple settings for controlling multiple functions of a computing device. The switch can include multiple flexible surfaces that each includes a surface contact. When the switch is depressed, at least one of the flexible surfaces can collapse and close a connection of the switch. When the switch is further depressed, multiple flexible surfaces of the switch can collapse and close multiple connections of the switch. As a result, depending on the amount of force by which the switch is depressed, different functions of a computing device can be controlled by the switch.

Provided is a switch that can be downsized. A switch is provided with a plunger, and an upper torsion spring configured to bias the plunger in a returning direction. The torsion spring has a first arm that extends to the plunger and abuts against the plunger. The plunger has a hole at a position into which the first arm is inserted. The hole is a through hole extending in a direction that is perpendicular to a direction in which the plunger moves, and is the same as a direction in which the first arm extends when viewed in the direction in which the plunger moves.

Provided is a switch that can reliably bring contacts into contact with each other with a small load, and can be prevented from malfunctioning. A switch is provided with a plunger, a lower torsion spring in which a biasing direction changes according to the movement of the plunger. The lower torsion spring biases the plunger in an opposite direction to a returning direction when the plunger is in the operation position, and biases the plunger in a direction different from the opposite direction to the returning direction when the plunger is in the reference position.

An apparatus and method for simultaneously operating the horn and light systems of a motorized vehicle is provided. The controller used to operate the systems can be a single controller that operates the horn when a certain range of pressure is applied to the controller and operates the horn and lights systems when a stronger pressure is applied. The system can include a dedicated horn operating system controller independent of the dual function controller to eliminate the need for differing pressures to operate the horn and light systems substantially simultaneously. Also disclosed are apparatuses and methods to coordinate a vehicle braking system with the vehicle horn and light systems to improve the reception of safety and/or emergency warnings.

An electrical multiple stage switch assembly includes an assembly casing, a first component carrier, and at least one multiple stage switch including a first disc contact, at least one second disc contact, and an actuator. The first and second disc contacts are positioned with their centers substantially aligned, and the first and second disc contact are adapted to flex into an electrical connection when the actuator is pressed and to flex back into a non-electrical connection when the actuator is released. A controlling member includes a controlling part for each switch, and the controlling part includes a spacing member adapted to limit the smallest possible distance between adjacent component carriers.
