A switch apparatus adapted to be disposed on a wall surface includes a box, a heat generating element, a cover, a switch element, and a first heat dissipation structure. The box has an opening and is adapted to be embedded into the wall surface. The heat generating element is disposed inside the box. The cover is assembled to the box and covers the opening. The cover has a front surface and a rear surface opposite to each other. The rear surface faces toward the box, and the front surface is adapted to be exposed from the wall surface. The switch element is disposed on the front surface. The first heat dissipation structure includes first and second sections connected with each other. The first section is connected with the cover and exposed from the front surface, and the second section extends into the box and contacts the heat generating element.

An electronic dial apparatus includes a rotating operation member, a conductive member rotating with the rotating operation member, a conductive pattern having a plurality of conductive areas electrically insulated from one another, the conductive member being configured to slidably contact the conductive pattern as the rotating operation member rotates, and a mode setter that sets a plurality of modes in accordance with a set position of the rotating operation member. The mode setter sets one of the plurality of modes based on a combination of a plurality of signal levels that depend on a contact position between the conductive member and the conductive pattern. The mode setter sets at least one of the plurality of modes for two combinations of the plurality of signal levels different from all combinations of the plurality of signal levels corresponding to each set position of the rotating operation member.

A device for a rotary haptic interface including: a rotary button and an interaction member interacting with a magnetorheological fluid, the rotary button and interaction member being secured to a shaft for rotation therewith, a chamber defined by walls and containing the fluid and the interaction element, and a mechanism generating a variable magnetic field. The element for interaction with the fluid includes a skirt surrounding the shaft, the skirt being secured to a longitudinal end of the shaft opposite the end to which the rotary button is secured, and extending from the first end towards the rotary button. The shaft passes through a single wall of the chamber and a sealing mechanism is arranged between the shaft and the wall. A mechanism for guiding the rotation of the shaft is arranged around the shaft between the sealing mechanism and the rotary button.

The present disclosure provides an intelligent lighting control system. The lighting control system detects a temperature reading from a temperature sensor of each light control module in a plurality of light control modules. Each light control module in the plurality of light control modules is configured to cause a transmission of a quantity of electrical energy to a lighting circuit of a light fixture electrically connected to the respective lighting control module. The lighting control system controls at least one of a heating and an air conditioning system to adjust heating or cooling based on the temperatures detected by the temperature sensor of the light control module.

In a switch unit which is equipped with a seesaw switch and a rotary switch, the seesaw switch and the rotary switch are arranged in a manner so that an axis of a swing fulcrum, i.e., swing shaft, of a knob, and an axis of a rotary shaft of a wheel intersect one another.

A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.

In a power seat operation device, a slider that is supported so as to be slidable in a radial direction with respect to a dial slides toward the radial direction center of the dial during rotation of the dial. A knob engagement portion that is provided to the slider is thereby disposed between a pair of slider engagement portions that are provided to a knob. This enables rotational operation of the knob to be restricted. However, during rotational operation of the knob, one out of the pair of slider engagement portions opposes the knob engagement portion from toward the radial direction center of the dial. This enables rotational operation of the dial in conjunction with sliding of the slider to be restricted.
