Installing a wired switch in a solid brick or concrete wall or installing on a plaster or tiled wall requires delicate routing and drilling to create a channel in the wall for the wire and space for the switch and switch box inside the wall. This routing and drilling work could damage the surface, causing expensive repair work. Wireless ...
Two light switches in one box. The switch on the right is a dimmer switch. The switch box is covered by a decorative plate. The first light switch employing "quick-break technology" was invented by John Henry Holmes in 1884 in the Shieldfield district of Newcastle upon Tyne. [1]
A thyristor dimmer rack An electrical schematic for a typical SCR-based light dimmer Solid-state , or semiconductor , dimmers were introduced to solve some of these problems. Semiconductor dimmers switch on at an adjustable time (phase angle) after the start of each alternating-current half-cycle, thereby altering the voltage waveform applied ...
A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may be dimmable, allowing the brightness of the lamp to be ...
A "T-rated" wall switch (the T is for Tungsten filament) [9] that is suited for incandescent loads. When turned on, an incandescent lamp draws a large inrush current of about ten times the steady-state current; as the filament heats up, its resistance rises and the current decreases to a steady-state value. A switch designed for an incandescent ...
A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...
A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
