Switches & Sockets - FAQs

What are one, two and three gang switches?

This just refers to the number of switches that are present on the plate. Normally in a domestic setting, you'll see one or two gang switches, but if you're installing new electrical switches, you could choose to have three or four gang switches installed.

What are rocker switches?

A rocker switch is one of the most common types of switch. It works by breaking and reconnecting the electrical circuit as it "rocks". Flipping the switch in one direction causes it to break the circuit, and in the other direction, it connects the circuit.

What is a dolly switch?

A dolly switch is sometimes known as a toggle switch. It uses a projected manual lever (which resembles a tiny gear stick) as opposed to a rocker. Pushing the lever up and down turns lighting on and off - however, they can also be used to provide power to other electrical appliances that use an on/off switch mechanism.

What is a spur switch?

A fused spur is a type of radial circuit which is taken from the ring main. This means it is usually used to provide power to a fixed piece of electrical equipment, like a fridge or a washing machine. Just like our other switches, spur switches can come in a range of different finishes from matte white and black, through to antique brass and pewter - so you can select exactly the right style to match your decor.

What is a dimmer switch, and how do they work?

The basic principle of a dimmer switch has been around for a long time. The most basic models reduce the amount of electricity that flows through the circuit, powering the light, which reduces its brightness. However, more modern dimmers actually work with the alternating current (AC) and switch if on and then off. This process diverts electricity from the bulb and reduces the overall current flowing through the bulb. At Arrow Electrical, we offer dimmer switches in a range of sizes and styles, amongst the most popular is the Heritage Brass range, but you are sure to find the ideal colour to match your interior design.

How are screwless switches fitted?

Screwless switches generally come in two parts. The first part is fitted to the wall with screws, as normal. The second part is a faceplate that fits over the top of the initial switch, clipping neatly on top to give a screwless appearance.

What is a two way switch?

Most typical light switches in the home are one way - that is, there is one switch to control a particular light fitting. However, in some situations, you might want to be able to control a particular circuit from two different locations. A great example of this is at the top and bottom of a staircase. That is where two-way switches come in, as they can be fitted into the circuit to allow it to be controlled from multiple locations.
