VETI3 1 Lever 1 Way Switch Graphite 4×2

In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord.

Switches for lighting may be used in residential and commercial buildings usually have wall-mounted light switches to control lighting within a room. Mounting height, visibility, and other design factors vary from country to country. The switch mounting boxes, or enclosures are often recessed within a finished wall. Surface mounting of enclosures is also fairly common though is seen more in commercial industrial and outbuilding settings than in residential structures.

The switches may be single or multiple, designed for indoor or outdoor use. Optional extras may include dimmer-controls, network modules, blank modules and 2-way modules.

The switch terminals are clearly numbered with a corresponding wiring diagram on the side of the switch to make installation and connection as simple as possible. The switch terminals use a clamping mechanism as opposed to a screw connection in order to prevent stranded cable from breaking and coming loose. The switch terminals come with 2 holes per terminal to make it easier and safer to insert 2 wires when bridging is required.
