Switches are a basic and critical component of most modern manufacturing systems, computers, and all types of appliances. A rocker switch comprises a lever that can be adjusted to either open or close electric circuits, thereby starting or stopping a designated action or process. The name itself is derived from the fact that it closely resembles a rocking chair in its design and movement.

 

Since rocker switches can be found virtually everywhere, including commercial and residential settings, we should all understand the signs that tell us whether or not they are functioning properly. Knowing this will go a long way in making our lives easier and safer as we will not only avoid potential safety hazards, but save potentially large amounts of time and money that would otherwise go towards repair and replacement costs. In this article, we’ll explore the various signs and indicators that tell us how well a rocker switch is doing its job.

 

Let’s jump right in.

 

How Do I Know a rocker Switch is Faulty?

There are various signs and indicators that we can rely on to tell us when we’re having trouble with a rocker switch, including:

 

Warm switches: When you discover that your switch is warn after you use it, it might be an indication of underlying problems. Faulty circuits are the usual cause for this kind of electrical fault, and might be a sign of potential electrical risks.

Non-responsiveness: A switch that does not respond immediately once you activate it should be investigated immediately as it will be a sure sign that something is wrong. The circuit will likely be remaining incomplete even after you activate it.

Loose switches: A switch that has been dislodged or broken can start moving and jiggling around in its socket which might negatively affect its performance. This looseness may also represent an electrical hazard.

Lights flickering: Any appliances or lights that are operated using rocker switches should operate smoothly and consistently. Flickering lights or stuttering appliances will be a sign that your circuit connections are functioning intermittently, which is a sure warning sign.

 

How to Test a Rocker Switch’s Functionality

You do not need to bring in an electrician in order to figure to whether or not it is functioning properly. If you have a multimeter nearby, you can use it to evaluate the functionality of simple circuits and switches. Here’s how to use a multimeter effectively:

 

Collect a screwdriver, electrical tape, multimeter, and any other equipment you feel you might need for the task.

Switch off the device and disconnect it from the mains power source.

Using the multimeter, disconnect all the connected appliances from the outlet.

Take the multimeter and connect it to the two opposing ends of the switch you’re examining.

Calibrate the multimeter settings so that it holds in a continuous mode and delivers fluid readings.

Push the rocker back and forth as you continuously monitor its readings.

Should the readings you receive hold steady, you can trust that your switch is not defective.
