Understanding the Different Types of Electrical Switches

With all the appliances that we have in our homes today, having the proper electrical switches to plug all of them is essential. Standard electrical switches are usually 15-amp, which is the standard plug for small appliances. Larger appliances such as washers and dryers require special outlets.

If you are in the market after an electical switch for your home, it is important that you become familiar with different electical switch models available so you can choose the right electrical switch for your needs.

Types of Electrical Switches
If you are looking for electrical switches for a new home in the process of building, you will have a larger variety of configuration options than choosing for a home already built (modifications may be allowed). Keep in mind that the device which is to be plugged into an electrical switch must match the socket’s capability.

Single Pole
A switch with a single input and output is used to control just one circuit. It turns the light on and off from one location, is easy to use, and is the most common type of switch found in homes.

Double Pole
Similar to single pole switches that are mechanically operated by the same knob, lever or button, the double pole switch is used to control separate circuits. These are also easy to use.

Three Way
A switch that consists of two brass screws, a dark colored screw and a green screw and it can control light from two different locations. This type of switch does not have toggle handle switch because one position doesn’t necessarily need to be on or off – it depends on the position of another switch.

Four Way
This switch has four terminals, each with two pairs of travelers. If a four way switch is what you need, you should consider hiring a professional because its installation is more complicated.

Multi Location Switch
A switch that is the interconnection of two or more electrical switches. It is used to control an electrical load from multiple locations, for example, this allows lighting in a large room to be controlled from different locations.

Dimmer Switch
A switch that allows you to adjust light levels in the room all while saving energy and extending the bulb’s life.
