A switch unit includes: a tactile switch; a cable which transmits an operation signal generated when the tactile switch is operated; a formed part where a fitting engagement portion which is disposed on an operation section exterior member at a predetermined position, a recessed surface which is formed on a side of a first end portion with respect to the fitting engagement portion and where the tactile switch is mounted, a cable fixing portion which is disposed on a side of a second end portion which is a side opposite to the first end portion with the fitting engagement portion positioned between the first end portion and the second end portion and to which the cable is connected, and a circuit which electrically connects the recessed surface and the cable fixing portion to each other and transmits an operation signal generated by the tactile switch to the cable are formed.

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.

An endoscope including a handle housing having apertures for legs of an operating part, an electrical switch positioned in the handle housing and having a carrier board having apertures for the legs. The operating part includes a finger pad having a finger surface, a ring connected to and extending from the finger pad, the ring having a plunger aperture, legs connected to and extending from the ring, the legs each having a spacer section and an electrical switch retention protrusion. The legs traverse the apertures of the handle housing and the carrier board to secure the electrical switch to the housing handle. The finger pad comprises elastically deformable material configured to extend toward and cause actuation of the electrical switch, when pressure is applied and to return to a rest position when pressure is released.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

A radiation therapy system includes an X-ray imaging system that is configured with a combined and simplified filter and collimator positioning mechanism. In addition, an X-ray imager of the RT system is only positioned at a few discrete locations within a plane that is a fixed distance from the imaging X-ray source when generating X-ray images. As a result, for each of these discrete imaging positions, the simplified filter and collimator positioning mechanism positions a specific collimator-filter combination in a specific location between the X-ray source and the imager.

Example methods and apparatuses of controlling a user interface with a plurality of input mechanisms are disclosed. One example method includes causing a first set of input mechanisms in the plurality of input mechanisms to be visually emphasized via a first visual technique while a second set of input mechanisms in the plurality of input mechanisms is not visually emphasized via the first visual technique, receiving a user input via an input mechanism that is included in the first set, based on the user input, determining a third set of input mechanisms in the plurality of input mechanisms and a fourth set of input mechanisms in the plurality of input mechanisms, and causing the third set of input mechanisms to be visually emphasized via the first visual technique while the fourth set of available input mechanisms is not visually emphasized via the first visual technique.

A switch mechanism (12) includes a housing (16, 18) with a fenestration (21), a switch element (22) held in the housing, and a membrane switch held in the fenestration. The membrane switch includes a flexible membrane (20) and a rigid rib (26). The rib is constrained to linear movement by guides (37, 38) in the housing so that contact with the membrane causes the membrane to deform and the rib to translate to actuate the switch element.

This embodiment relates to a button module having a sterilization function. The button module according to one aspect comprises: a cover including an opening; a housing being coupled to the cover; a button body disposed inside the housing, including a first body and a second body selectively exposed to the outside through the opening; a rotation shaft for rotating the button body; a printed circuit board disposed at a rear side of the button body, the printed circuit board including a switch and a germicidal lamp irradiating light toward the button body; and an elastic member disposed between the rotation shaft and the first body and between the rotation shaft and the second body.

An operation switch includes a concave portion in which an inner peripheral surface is constituted by a first inclined surface that is reduced in diameter toward a bottom portion from an external surface of a frame and a cylindrical portion that is formed in a pressing type operation button mounted on the concave portion and in which an outer peripheral surface is constituted by a second inclined surface that has a gradient larger than a gradient of the first inclined surface and faces the inner peripheral surface of the concave portion.
