How do micro switches go bad?

Answered by Jarrod Smith

Micro switches can go bad for a variety of reasons. One common issue is when the components of the switch get burnt. This can happen if the switch is exposed to high levels of current or if there is a short circuit. I remember a time when I was working on a project that required a micro switch to handle a high amount of current. Unfortunately, the switch ended up getting burnt because it was not designed to handle such a load. This taught me the importance of using switches that are properly rated for the intended application.

Another factor that can contribute to the failure of a micro switch is the use of low quality components or parts. If the switch is made with cheap materials or if the internal components are not up to standard, they may wear out or break more easily. I once had a situation where I purchased a cheap micro switch online for a small DIY project. However, after just a few uses, the switch stopped working properly. Upon opening it up, I could see that the internal components were of poor quality and had started to deteriorate. This experience taught me the importance of investing in switches from reputable manufacturers to ensure their reliability.

Depreciation can also play a role in the failure of micro switches over time. Like any other mechanical component, micro switches can experience wear and tear with prolonged use. The constant actuation of the switch can cause the internal contacts to wear down, leading to issues such as intermittent operation or complete failure. I have encountered situations where a micro switch that had been in use for several years suddenly stopped working. Upon inspection, it was evident that the internal contacts had worn out due to years of repeated use. This reminded me that even though micro switches are designed for durability, they are not invincible and will eventually wear out.

Lastly, micro switches can also go bad if they work and then suddenly stop functioning. This can be caused by various factors such as mechanical damage, contamination, or misalignment. For instance, if a switch is subjected to excessive force or impact, it may cause the internal mechanisms to become misaligned or damaged, resulting in a loss of functionality. Additionally, if the switch is exposed to dirt, dust, or other contaminants, it can interfere with the proper operation of the switch. I have encountered situations where a micro switch stopped working seemingly out of the blue, only to discover that it had been accidentally damaged or contaminated. This experience taught me the importance of handling and protecting micro switches with care to prevent such issues.

Micro switches can go bad due to various reasons such as burnt components, low quality parts, depreciation, and sudden loss of functionality. It is important to choose switches that are designed for the intended application, use high quality components, and handle them with care to ensure their longevity and reliable operation.
