Do you want to find out how to check your micro switch? There is absolutely no need trying to rack your brains about how this process can be carried out since this post will be helping you out today. It will be revealing how to tell whether a micro switch is faulty or not. After checking out the details below, you will be in a much better position to tell whether your micro switch is intact or not. It means there won't be any need for guesswork.

Faults that could be wrong with your micro switch

Before making the decision to check your micro switch, it is important to find out some possible faults that can affect it from functioning optimally. You need to understand that while some of these faults can be addressed and resolved, others cannot. This means while you can hire a repairer or decide to fix some of these problems on your own, nothing can be done to improve such electrical switch when some problems are experienced.

The faults that can affect a micro switch are components getting burnt, low quality components/parts, depreciation, when the switch works and stops suddenly. Although there are other faults, it has been discovered that over 70% of micro switches usually experienced these issues.

How to check for faults

The process of checking for faults in micro switches is so simple that anyone can do it. There is no special knowledge or skill required to get going. Below are some tips that can help you out today. Just apply them wherever necessary on your micro switch and you will be fine.

Step 1 - Separating the plastic

There is a plastic material used to encase micro switches. This can be done through several means. The reason why the plastic materials need to be separated is to ensure you are having a very clear view. Simply put, it will enable you to see how the micro switch components have been assembled. You can make use of a drilling tool for this purpose.

It still depends on the type of micro switch since some can be separated without using any drilling tool. Just drill gently in order to separate both materials. For instance, there are micro switches which are held together through friction. These can also be separated. Don't worry about them splitting especially when they have been screwed against their supporting brackets.

Step 2 - Taking pictures

You may be wondering what picture has got to do with micro switches. The truth is that this is very important especially if you don't want to damage such electrical switch beyond what it is at the moment. Most people who have attempted to open their micro switches usually encounter one problem. This is the challenge of not being able to assemble them as they were.

This is where taking pictures will become very necessary. It helps you to know how the components of your micro switch were assembled originally before being dismantled. This makes your job much easier given that you won't become confused about how such parts can be assembled in the most effective way later on. If you haven't mastered the process of dismantling and assembling of micro switches, this is one step to be taken seriously. You can make use of the camera in your mobile for this purpose since there is no need having any of those fancy cameras.

Step 3 - Checking the components

After taking pictures of your micro switch, you can then start checking the components one after another. This is where you have to ensure every component has been properly checked to know what could be wrong. Failure to do such can lead to wrong assumptions about whether the micro switch is working or not.

Also, you need to check whether the components are contacting as expected or even well positioned. Sometimes, one component being faulty inside a micro switch can lead to malfunctioning. If any part is damaged, it is recommended to have it replaced. This will make it start working once again.

Step 4 - Cleaning the components

When micro switches have worked for a long period of time, there is every chance that dirt can begin to accumulate in them. This is an opportunity to have its internal parts cleaned for optimal functioning. It is basically all about cleaning the contacts.

In case you aren't comfortable with cleaning the parts or there seem to be some stubborn stains, it is possible to have them soaked inside water (50% green diluted) for around 60minutes. This cleaning method is more effective and can remove 80%-90% of stains.

Step 5 - Re-assembling

Once you have checked the parts and discovered what could be wrong with such micro switch, it is high time you had it assembled the way it was originally. There is nothing special required in getting this step completed. All you need to do is have the pictures that have been taken earlier on looked at in order to know how the components have been arranged.

In case you are still finding it hard to check, hiring an expert won't be a bad idea.
