China Micro Switch Manufacturer Tell You Why Micro Switch Is Not Working

Micro switch is one of the most reliable amongst other switches. Apart from being able to carry out various functions in appliances and devices over the years, they have proven to be very effective. It is one of the reasons why companies are choosing their option more than ever before. They are highly sensitive to changes which take place in appliances. This makes them determine how current flows amongst components over a given period of time. 

Having said all of these, it is crucial to note that a micro switch may malfunction or not work as expected. Such an instance can bring about confusion and frustration especially when you do not know the right steps to take in order to make it start working again as expected. There are people who have complained of not knowing what to do whenever their micro switch seemed to have developed one fault or another. 

Are you amongst such category of people? Do you know that there are various ways to handle such an issue? This post will be revealing some of the things you can do to make your micro switch start working. Just ensure to read the details of this post from beginning to the end. It will help you have a clue about how to fix such challenge anytime it is experienced.

Checking the connection 

To most people connecting a micro switch is one of the most confusing tasks. This is not true especially when you know the right steps to take. One thing is certain about micro switch which is the fact that if you get the connection wrong, your device or appliance will not work as expected. In order to avoid such a scenario, it is very crucial to get it right from the onset. 

For instance, it is very important to know which wire should connect “Common” and battery. Also, know the wire that will connect the battery with “Normally Open” and “Normally Closed”. Without this knowledge, it will be very hard to connect a micro switch and expect it to work in a normal way. 

Most of the time, micro switches fail to work due to wrong connections. The operators have connected the wires wrongly. It can be very frustrating to start an electrical project only to get stuck in the middle of it because you do not understand how to make the right connections. It is therefore recommended that you learn how such connections are made in order to be on a safer side. 

When a micro switch is connected the right way, two things are always expected to happen. These are current will flow into components of your device as expected whenever its switch is pressed or it will become very sensitive. If you do not experience any of these two functions or roles, there is something definitely wrong with your connection. 

Checking the terminals 

It is true that micro switches can carry out lots of functions from being sensitive and regulating the flow of electricity amongst various components. However, one thing that you have to understand is the fact that such functionalities start from the terminals. In case you do not know, they are those points where wires are connected to in a micro switch. Micro switch terminals are very sensitive and require to be connected properly. Once this is not done, there is the problem of experiencing partial connection or contact. 

A problem like this can cause your device or appliance to malfunction at will. There are worse case scenarios which can bring about damage in the components of a device. This is one problem that can cause further damage thereby making you to spend more than necessary in the long run. A micro switch terminals are very crucial when it comes to how it will work as expected. 

How have you connected the terminals? In other words, always ensure that the wires or metals are soldered. Do not ever fall into the temptation of wrapping the wires to the terminals without considering the option of soldering. This is because as time goes on, the wire may become loose thereby leading to failure of such switch. It is the reason why soldering is always recommended. 

Although this process may take time to complete as compared to having the wires wrapped around the micro switch terminals, it will definitely stand the test of time. As a matter of fact, soldering ensures that you will not experience any problem of partial contact. 

Checking your device components 

Micro switches may be one of the best options based on how they work in appliances. For instance, they can carry out roles of a detector or sensor. However, it should be noted that without a functional component, there is very little your micro switch can do. In other words, micro switches can only work when the components of your device are functioning as expected. 

If your device components are faulty or not working, there is no how a micro switch can be very effective. Try to check which of the components are bad or faulty and repair such as required to ensure the benefits of a micro switch. With working components, there is every chance that your micro switch will last as long as possible. 


This is probably one of the most effective solutions you can adopt to fix any problem related to micro switch not working as expected. It is possible such switch is bad or faulty. In this case, it will not work as expected. This solution is only recommended once you have tried out the other ideas suggested above without any tangible success. In such case, try to ensure the micro switch is replaced.

Based on the above details, it is very obvious that a micro switch can stop working due to several reasons. However, there are various ways to make it start working again which were suggested. Just as explained, ensure to try out each of them for best results. Do not replace a micro switch without checking how its terminals have been connected.
