Not Sure Which One You Need? How To Avoid Mistakes When Choosing An AC Current Switch

If you need a new AC current switch, and you've never purchased one before, take your time to get it right. The last thing you want is to purchase the wrong current switch for the job. Before you purchase your current switches, here are four steps that will help you make the right selection.

Check for the Right Current

If this is your first time purchasing a current switch, make sure you check for the right current. There's a big difference between an AC and a DC current switch. While they both control the electrical current, they do so from opposite pathways. With DC, or direct current, the electrical charge flows in one direction at all times. However, with AC, or alternating current, the electrical charge alternates direction from time to time. Before you purchase your switch, be sure you have the right one.

Know the Switching Speed

When purchasing a current switch, you also need to know the switching speed. That's the speed with which the electrical charge flows through the switch. If you're purchasing an AC current switch, you need to be concerned with two specific speeds: the directional speed and the magnitude speed. For maximum performance, you want a quicker switching speed since delays can lead to extended electrical arc time, which can cause overheating. If your current switch overheats, you could end up with an electrical fire.

Choose the Right Load Type

When choosing a current switch, you also need to make sure you get the right load type. To do that, you need to know if you'll be working with a resistive or inductive load. Both types of loads require a specific type of current switch. Electric devices such as heaters will require current switches for a resistive load. However, larger devices such as motors will require current switches designed for inductive loads. Choosing the wrong load type for your current switch could result in immediate failure and malfunction.

Avoid Non-Certified Switches

When it comes to choosing the right current switches, avoid purchasing devices that are non-certified. Non-Certified switches have not been tested for performance, which means they may not meet appropriate safety standards. To avoid problems with your switches, always choose devices that are certified for safety. When you purchase certified current switches, you know that they meet safety and performance standards for electrical and mechanical functions.

Don't get stuck with the wrong current switches. Use the tips provided here to help you choose the right switches for the job.
