Here is the major challenge 

One of the benefits of rocker switches is the fact that they can help regulate the current or voltage that comes into your device. This is to help prevent situations related to power surge. Despite all of these benefits, it has been discovered that most people do not really understand how to get the best from their rocker switches. For instance, they do not know much about when these switches have been switched on or off. 

In case you happen to be amongst these people, there is no doubt that you have come to the right place. This post will be revealing some facts about rocker switches being turned on/off. After checking out the details below from start to finish, you will definitely understand your rocker switch much better. 

What you should know

Before delving into the major details of this post, it is very crucial to understand some important facts about rocker switches. This has to do with how they have been built or structured to work. Although they are designed to toggle back and forth, it is possible for them to maintain one position at a time. For instance, there is no rocker switch that maintains two positions simultaneously. In other words, it is either one side of the button is pressed down while the other remains upwards or the other way round. The diagram below will explain this fact about rocker switches in a much clearer way. 

It can be seen that one side the rocker switch has been pressed downwards while the other side remains upwards. It is only a sign that a rocker switch can either maintain a state of being switched on or off. If the other side is pressed downwards, you will notice the former side will now remain upwards. 

How To Know If Your Rocker Switch Is On or Off

When it comes to knowing whether a rocker switch is on or off, there are people who usually make this process complicated. These will be explained below:

Using the universal standard 

Using the normal standard 

The universal standard 

Normally, switches are expected to be manufactured or produced according to universal standard. This includes a rocker switch. When this happens, they will have two symbols such as“–" and “O”. You will notice that the picture above has these symbols. As a matter of fact, it is simple when a rocker switch has these symbols present. 

For instance, when the side with “–" symbol has been pressed down in a switch, it means the device is working. In other words, your rocker switch has been switched on. In a nutshell, the “–"symbol simply implies “on”. It is the point when contacts are closed in the rocker switch to enable flow of electricity into your device or appliance. 


On the other hand, the symbol that carries “O” is indicating the switch is not working when it is pressed downwards. This is the point whereby there is open contacts. It means there is circuit breakage to ensure your device or appliance is not working. In simple terms, “O” is that point which signifies that a rocker switch has been turned off. 

A close look at the diagram above will tell you the rocker switch is already maintaining an “ON” position. This is because just as explained above, the side which carries “–" symbol has been pressed downwards while the other symbol of “O” remains upwards. 

Using the normal method 

This method will prove helpful especially for people whose rocker switches do not have the symbols that have been explained above. In such a case, you may have to watch out for some things in your appliance in order to know when the rocker switch has been turned on or off. 

Did you notice the above rocker switch does not have any of symbol like “–" and “O” as compared to the first picture? In this case, you may find it hard knowing when it is on or off since there is no sign to indicate such position. There is no need to be bothered as it is still very much possible to know whether such switch is working or not. 

In most cases, you will find that rocker switches are maintaining “on” position when the upper sides have been pressed downwards. The above picture is a typical example of such switch. Notice that the picture below is also showing a similar position?

Alternatively, you will discover that there is a on and off inscription at the top and bottom of the rocker switch respectively. This will help you know which direction represents on or off in such switch.

Another way to find out

In case after checking out the above methods and you are still not sure how to know whether your rocker switch is maintaining a “on” or “off” position, it is recommended to check whether your device is working. For instance, stabilizers make use of rocker switches. Most times, these do not have the symbols explained above. The best thing to do is wait for some time after pressing one side of the button downwards. Such time will help you know whether the device is working or switched off. 


Based on the above, it is very obvious that there are several ways to find out if your rocker switch is actually switched on or off. Just follow the details above one after another in order to make the most of such switch.
