What Is A Waterproof Micro Switch In A Rice Cooker And How Does It Work?

Most people understand the fact that micro switches are very versatile when it comes to their uses. These switches have managed to change how devices function when being used. However, the truth is that there are appliances that are not common whereby they seem to be performing advanced functions. One of such electrical appliances is rice cooker. Of course, you may know how this device has been built to work. However, there is no doubt that you are not aware micro switch plays a major role in such features and functionalities. 

Are you wondering how micro switch works in a rice cooker appliance once installed? Do you know that this process is very easy to understand? This is the right place where everything about micro switches and rice cookers will be explained. After reading the facts to be revealed below in this post, you will have a much better understanding about how a micro switch functions inside rice cookers. 

Just as said above, it is very simple to understand. In other words, there is no rocket science about the entire process. However, for a much better understanding, it is recommended you have a rice cooker device.

What is a rice cooker?

A rice cooker is an appliance that is automated and has been built to help steam rice. Of course the world is advancing at an amazing pace right now. Technology seems to be advancing too and rice cooker has been a typical example of its progress in recent years. In case you want to cook your rice but do not have the time and strength to be doing such manually, rice cookers are the perfect option to explore. These are electrical appliances which have been built to ensure the process is fully automated. From the steaming to cooking process, you will not have to lift a finger. 

Most rice cookers have some major features and components. These are thermostat, bowl and heating source. For these components to start working, users are expected to have their buttons switched on. Once this has been done, the automation process will commence. The best part about rice cooker is the fact that you do not have to bother about monitoring the rice. In other words, there is no need checking whether it is ready to be switched off or not. 

How does this concern micro switch? 

You may be wondering how the above explanation concerns a micro switch. If you have to know, it has everything to do with micro switch. One thing most people do not know about these switches is the fact that they function or work in two major ways. These are operating as button switches and monitoring devices. Just as said above, a rice cooker has thermostat. This enables it to carry out automatic functions. Such could be turning off automatically once the rice has been cooked to a particular temperature. 

The role of a thermostat is to ensure automatic switching on and off in a device. This is made possible through the presence of a micro switch. For instance, once the rice gets hot up to a certain temperature, it will go off. It is the micro switch that is enabling such role to be played to perfection by the thermostat.  

A micro switch can detect how components are functioning. Once this has been done, it will dictate whether normally opened or normally closed will be affected. For instance, when the rice has been heated up to a particular level, it means the cooker will have to be switched off automatically. This is where the micro switch will maintain a normally open contact point. At this point, electricity will not flow. This means the rice cooker is switched off automatically. 

On the other hand, when the rice cooker is working (that is switched on), it means the normally closed contact point has been activated. It is the point whereby there is electricity flow amongst components. 

What about the other functions? 

Apart from playing the role of monitoring how a rice cooker device functions when being switched on, micro switches can also be used in other aspects. This is very obvious in the buttons of a rice cooker. For it to be switched on, you will need to press some buttons. These buttons are being made to work through the installation of a micro switch

Just as the buttons are being pressed, normally closed or normally open contact points can be activated. It is similar to the explanation above about how these switches carry out detector functions. For instance, when you press the button after putting rice inside the appliance, it will be start working. This means that it is maintaining a normally closed contact position. 

On the other hand, pressing the button again can make the rice cooker to be switched off. This simply implies that normally opened contact point has been activated. In other words, there will not be flow of current. 

Based on this explanation, it can said that micro switches carry out two major functions in rice cooker appliances. These are manual and automatic functions. When the manual function is activated, such can be controlled by automatic function and vice versa. For instance, when the switch button is pressed, you do not have to monitor how the rice is being cooked. Instead, it can switch off automatically once it has been perfectly cooked for consumption. 

On the other hand, when the rice has not gotten to the point where the device will be switched off by the thermostat, it is possible to have it switched off manually.

Based on the above, it can be seen that micro switches are very crucial when it comes to how rice cooker appliances have been designed to function. Just as explained above, modern devices can hardly function properly without the inclusion of micro switches. They are majorly responsible for carrying out those automated functions you experience in these appliances.
