A push switch includes a movable contact member, a first fixed contact, and a second fixed contact. The push switch is in a first contact state in a first contact position where the movable contact member contacts the first fixed contact, and is in a second contact state in a second contact position where the movable contact member contacts the second fixed contact. The push switch is not switched to an on state in response to transitioning from an off state to the first contact state, and is switched to the on state in response to further transitioning to the second contact state, and the push switch is not switched from the on state to the off state in response to the second contact state being released, and is switched from the on state to the off state in response to the first contact state being further released.

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.

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.

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.

A button structure comprises a base layer, a supporting structure arranged on the base layer, an elastic film layer, the elastic film layer covering the support structure and connected to the support structure, the support structure and the elastic film layer defining a cavity above the base layer, a first upper electrode arranged on the lower surface of the elastic film layer and located in the cavity, a first lower electrode, arranged on the base layer and located in the cavity, and a first variable resistance elastic body between the first upper and first lower electrodes, either arranged on the lower surface of the first upper electrode or arranged on the upper surface of the first lower electrode. When the elastic film layer is elastically deformed in the direction of the base layer, the first variable resistance elastic body connects the first upper electrode with the first lower electrode so as to generate a first signal related to the elastic deformation of the first variable resistance elastic body.

A treatment system includes: a treatment instrument for cutting living tissue in a liquid; and a controller for performing control, prior to cutting the living tissue with the treatment instrument, to suppress reduced visibility of a treatment area due to turbidity in the liquid caused by the cutting of the living tissue based on preparation information regarding cutting preparation for the treatment instrument.
