15 Facts About Light switch

In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets.

The Light switch mounting boxes, or enclosures are often recessed within a finished wall.

The "quick-break" Light switch overcame the problem of a Light switch's contacts developing electric arcing whenever the circuit was opened or closed.

Contacts of a Light switch are under their greatest stress while opening or closing.

Therefore, any Light switch has a finite life, often rated at a given number of cycles of disconnection at a specified current.

The contact area of the Light switch is constructed of materials that resist corrosion and arcing.

Push-button light switch has two buttons: one that closes the contacts and one that opens the contacts.

Push-button Light switch reproductions are available on the market today for vintage or authentic styling.

All of the Light switch mechanisms have no exposed metal parts requiring grounding .

The contact terminal set screws are installed at a slight angle to allow easier screwdriver access after the switch mechanism has been installed into a wall-plate - before fixing the wall-plate to the wall.

Each Australian rocker Light switch mechanism is actually a single-pole, double-throw Switch, known as a "two-way Light switch", and has three terminals.

One form of mercury light switch uses a sealed glass vial that is tipped by the toggle lever, causing a drop of liquid metallic mercury to roll from one end to the other, bridging a pair of contacts to complete the circuit.

Light switch combined with a light socket is sometimes installed in basement or utility areas of homes.

Dimmer Light switch, properly called a dimmer control, contains a solid-state circuit to allow changing the brightness by reducing the average voltage applied to the lamp.

Wireless light switch provides remote control of lighting using a hand-held transmitter.
