Reasons for poor contact of micro switches and its solutions

Micro switches are ubiquitous in our daily life, and they play an important role in various devices such as electronic equipment, household appliances and automobiles. However, sometimes we may encounter the problem of poor contact of micro switches, which not only affects the normal use of the equipment, but also may cause damage to the equipment. So, what is the reason for poor contact of microswitch? And how to solve this problem?

First of all, we need to understand what is a micro switch. Micro switch is a small switch, its working principle is through the internal metal contacts contact or disconnect, so as to achieve the circuit on and off. Due to its small size, light weight, long life and other characteristics, micro switches have been widely used in a variety of equipment.

However, micro switches can suffer from poor contact during use. This is mainly due to the following reasons:

1. contact wear: prolonged use may cause the contacts of the microswitch to wear out, thus affecting its contact performance.

2. contamination: Micro switches with contacts that are contaminated with substances such as dust, oil, etc. may also result in poor contact.

3. Spring failure: A spring inside the microswitch that fails may prevent the contacts from making proper contact.

4. Improper installation: If the microswitch is not installed properly, it may result in the contacts not making normal contact.

So, how should we solve the problem of poor contact of microswitch?

1. Regular inspection: Check the contacts of the micro switch regularly for wear or contamination, and if so, clean or replace them in time.

2. Correct installation: Make sure the installation position of the microswitch is correct to avoid poor contact caused by improper installation.

3. Replacement of spring: If the spring of the microswitch is found to have failed, it should be replaced with a new one in time.

In a word, the problem of poor contact of micro switch is not complicated, as long as we check it regularly, install it correctly and replace the damaged parts in time, we can solve this problem effectively. Hope this article can help you better understand and use micro switches.
