Electrical Switches

Overview

The most fundamental of all electrical devices is the electrical switch. What makes them important in our day-to-day lives is their safe, efficient, and reliable operation. Utmost care must be taken to select an electrical switch, whether it is for industrial or home application. Be careful to select a switch that is appropriate as well as safe. The number of options that you get while searching for a correct switch can leave even an engineer confused. Switches are generally categorized on the basis of the arrangement of their contacts. Switches are described as one-way, two-way, three-way and four-way switches by electricians and electrical suppliers. Such kind of nomenclature has different implications in the UK and the US, however. A simple on-off switch is referred to as a one-way switch in the UK and a two-way switch in the US.

How it Works

The core function of a switch is to control the flow of power in an electrical circuit. The electricity flows through the circuit when the switch is on and powers the circuit. The switch can then be used for whatever purpose it was intended. Be sure to get a switch that meets national tests and accreditation standards. An appropriately rated switch comes with assured performance. The most commonly found switches are those that come in the toggle or snap form. If you have anticipated 2,000 annual operation cycles, be sure to look out for a switch that is tested for 50,000 cycles. Since switches are universal electronic components, you will find no difficulty in getting them. Most manufacturers of electrical and electronic components including Crouzet, Johnson Electric, Elma, Eaton, Panasonic, Bryant, and Allegro make electrical switches.

Benefits

It is hard to imagine a modern space without an electrical switch. A switch with the correct electrical rating and characteristics will stand the test of time. Factors such as perfect resistive and motor loads and tolerance of transient in-rush current on start up play a vital role in determining the safe and effective operation of your switch. Also, it is possible today to take your pick from a range of switches in different colors and blends.

Costs

The cost of switches depends on their design, components, and application. Switches meant for simple applications are really cheap. However, even the most high-end switches do not come with an expensive price tag. So, you can get a switch that meets your need the best without worrying about the costs. The cost of electrical switches ranges from $20-$150, depending on your preference.

Timing

The overall parameters of your project should be analyzed in order to determine the best time for installing switches. This is because electrical switches form a part of larger projects and are not treated as individual entities. So, you should do a cost-benefit analysis on the project before getting the switches.
