Micro switches have come into existence to improve the functionalities of devices and appliances over the years. That is to say, they are existing to ensure your devices are performing optimally via their detector and sensing roles. In case you do not know, there are numerous applications or appliances which can hardly function without the use of micro switches in them. It means their functions go beyond having bulbs turned on/off.  They are very advanced in terms of functionalities in lots of regards.  

One of the ways that micro switches are proving to be very useful is their installations in HVAC applications. Whether you want to acknowledge it or not, the truth still remains that the micro switches have played a very crucial role when it comes to helping these applications function in an advanced way. Are you doubting how this happens? If that is the case, ensure to read details of this post from beginning to the end. 

It will be revealing how a micro switch tends to work in various types of HVAC applications. After reading these facts, you will come to one conclusion – micro switches are more useful than they are being portrayed to be. 

What are HVAC applications?

Before understanding how micro switches tend to work or function in these applications, it is important to make some explanations on what HVAC applications are all about. These are devices or appliances which have been built to ensure that indoor air quality is improved. They are becoming very popular due to their functions when it comes to enhancing the quality of air in your home or office. In case you live in an environment where the air seems to be polluted, an HVAC application will be of great help in lots of regards. 

A typical example of an HVAC application is air conditioner. Its primary goal is to ensure that thermal comfort is provided. This is obvious since they have been designed to make rooms cooler and more comfortable to stay in. You can talk about the smart features that are being integrated into these applications at the moment. However, there is one thing that you have to understand. This is the fact that micro switches are helping them work in the most automated manner. The details below will be using an air conditioner for better understanding. 

How does a micro switch work in HVAC applications? 

Just as said above, air conditioner will be used to explain this process. Of course, you know that these applications work to ensure the temperature of a room becomes cold for some time. This means it is not a constant or permanent working process as the applications will have to pause after working for time depending on the settings and features. For such interruption to happen, a micro switch needs to be included. It is responsible for detecting changes in temperature and sending signals to other components thereby making the appliance to stop producing cold.  

In case you do not know, switches have the ability to sense changes in an appliance or environment and activate some certain functionalities. It is through their sensor ability which can determine whether there will be an interruption or not within the air conditioner unit. For instance, if the AC has been built to stop working after a room temperature reaches a particular degree centigrade, it is the micro switch which has the ability to detect such and make it happen. 

Once it senses that the temperature has been reached, it will cause the AC to stop working for some time. You must have noticed how an AC unit stops and starts after some time in your home. It is the micro switch that is at work. 

Control panel buttons 

Apart from their sensor abilities, micro switches are also included in the control panels of air conditioners which happen to be one of the most popular HVAC applications. When you press the buttons in such appliance, it is the micro switch that makes such possible. For instance, every HAVC application has a switch on/off button. All you have to do is have the button pressed and it will either start working or be turned off. This is could not have been possible without the presence of a micro switch at work.   

Even when you want to regulate some of their settings, such is possible through the control panels. As a matter of fact, majority of the buttons you press in these applications are being powered by a micro switch. 

How does this happen?

You must be wondering how the above happens right? This is very simple to understand as micro switches have two contacts – normally open contact and normally closed contact. In the case of a micro switch sensing changes within the AC and activating/deactivating the other components, these contacts have to play their respective roles to perfection. For instance, at closed contact, the air conditioner unit is working since it is the contact which sanctions the flow of electricity in a micro switch. On the other hand, the open contact is that position whereby there is no flow of electricity.  

It is the same thing when a micro switch is included in their control panels. The closed contact as explained above, allows flow of current/electricity amongst the various components. Therefore, as the buttons are pressed, you are either giving room for flow of electricity or interrupting such a process. 

It is important to note that when it comes to how micro switches work in these applications, one thing is always certain. This is the fact that such can be either manual or automatic. For instance, in the case of sensor role explained above, it works automatically. Their inclusion in control panels requires the pressing of buttons. Without pressing such buttons, they will not be activated. 

Conclusion 

The above explanation has proven that micro switches work in HVAC applications in a way that is very easy to understand. For a much better understanding, it will be better to observe your air conditioner unit which is a typical example of HVAC application.
