Knob on display (KoD) devices and related systems, methods, and devices are disclosed. A KoD device includes a touch surface including a conductive material. The touch surface is configured to be positioned in a released position and in a depressed position. The touch surface is configured to be positioned in the depressed position responsive to pressure applied to the touch surface. The KoD device also includes a push electrode pad configured to be positioned in engagement proximity to a touch sensor of a touch screen device in both the released position and the depressed position. The push electrode pad is electrically connected to the conductive material of the touch surface responsive to the depressed position and electrically isolated from the conductive material of the touch surface in the released position.

A wall-mountable load control device may include an illuminated rotary knob for providing a nightlight feature. The load control device may be configured to control an intensity of a lighting load. The load control device may include a yoke adapted to be mounted to an electrical wall box, an enclosure attached to the yoke, a faceplate attached to the yoke and having an opening, a mounting member attached to the yoke, and/or a potentiometer located within the enclosure and having a shaft extending through an opening in the yoke and the opening of the faceplate. The load control device may include a collar attached to the boss of the mounting member and surrounding the shaft of the potentiometer. The mounting member may be configured to conduct light from at least one light source housed within the enclosure to illuminate the faceplate.

A disconnector having a stack of modular contact boxes surmounted by a snap-action switch box, each modular contact box including a rotary contact and two fixed contacts which are accessible from the outside. The switch box further includes a driven indexing element which is rotatably associated with a spindle loading support and at least one spring connected between the two in order to load them elastically with respect to each other following a mutual rotation about the central axis. The disconnector has a single actuation rod which passes through all the modular contact boxes coaxially to the central axis and is fixed in rotation to all the rotary contacts.

One or more examples relate to a knob-on-display. An apparatus of such a knob-on-display includes a touch surface, a dome switch pad, a dome switch, a rotation electrode pad, and an electrically conductive structure. The touch surface may include an electrically conductive material, the touch surface movable to a released position and to a depressed position. The dome switch may include an electrically conductive material. The dome switch may be physically mounted to and electrically connected to the dome switch pad. The rotation electrode pad may be in engagement proximity to a touch sensor of a touch screen device in both the released position and the depressed position. The electrically conductive structure may be physically and electrically connected to the dome switch pad and the rotation electrode pad, the electrically conductive structure defining a continuous electrically conductive path from the rotation electrode pad, through the dome switch, to the electrically conductive material of the touch surface in both the released position and the depressed position.

A switch and methods of assembling a switch. The switch may include a housing; a first terminal electrically coupled to a power source; a second terminal electrically coupled to a load; a contact having a first contact end and a second contact end, the contact being operable to be in a closed position, in which the first contact end engages the first terminal and the second contact end engages the second terminal such that the contact electrically connects the first terminal to the second terminal, and an open position, in which the contact does not electrically connect the first terminal and the second terminal; and a biasing member configured to bias the contact towards the first terminal and the second terminal, the biasing member being operable to apply a first biasing force proximate the first contact end and a second biasing force proximate the second connect end.

A rotary encoder switch includes a cover cap, a fixing sleeve, a first base board, an actuating device, and a second base board disposed under the actuating device. The actuating device includes a base seat and a rotary element rotatably connected to the base seat and mounted to the cover cap. The first base board is disposed on the actuating device and has multiple first lighting elements. The rotary element is rotatable in conjunction with rotation of the cover cap so as to generate encoding signals according to each rotary position of the cover cap for controlling functions of an applied product. The first lighting elements are capable of emitting light in sequence subject to the rotation of the cover cap, while the light being emitted is permeable to the cover cap for users to easily recognize the exact rotary position of the cover cap.

A spring configured to be fixed to a housing and nested within a dial that is rotatable about the spring. The dial has a plurality of spaced apart inwardly facing teeth that are adjacent the spring. The spring is configured to facilitate rotation of the dial about the spring. The spring includes a central body having at least one anchor configured to connect the spring to the housing. The spring also includes at least one arm having a first end connected to the central body. The spring also includes a second end of the arm that is connected to a bulb. The bulb can be enclosed and include an exterior surface with a node that is on distal from the central body. The node is sized to fit in a space between adjacent teeth. The enclosed bulb biases the node toward the spaces between the teeth.

Base assemblies for knob on display (KoD) devices and related systems and devices are disclosed. A base assembly for a KoD device includes a base portion for positioning between one or more electrode pads and a touch screen of a touch screen device. The base portion includes electrically insulating material. The base portion further includes an exterior surface to face the touch screen, an interior surface to face the one or more electrode pads, and extender pads including electrically conductive material. The extender pads extend through the base portion from the interior surface to the exterior surface.
