The Fundamentals Of Micro Switches
You may have seen micro switches in different types of devices, but you may not know the full name of this product. The term micro switch refers to a miniature snap-action switch. The name is given because this type of switch requires a small amount of force to activate. In this article, we are going to get a deeper look into the background of these units. Read on to find out more.
First of all, it is important to keep in mind that these units can be found in numerous devices, such as appliances and electronic circuits. Since these products don’t require a lot of effort to activate, they can be a great choice for machinery, industrial equipment, microwave oven, and elevators just to name a few. Apart from this, they can be used in many vehicles. In fact, we cannot count the number of electronic devices they are used in.
As far as the origin of these products is concerned, they were introduced a long time after the advent of other types of units that perform the same function. For the first time, a micro switch was invented in 1932 by an expert named Peter McGall.
A few decades later, Honeywell Sensing and Control purchased the company. Although the trademark still belongs to Honeywell, a lot of other manufacturers make micro switches that share the same design.
How do They Work?
Due to the design of these units, they can open and close an electronic circuit in an instant. Even if a small amount of pressure is applied, the circuit can go on and off based on the construction and installation of the switch.
The switch has a spring system inside it. It gets triggered through the movement of the lever, push-button, or the roller. When a little bit of pressure is applied with the help of the spring, a snap action happens inside the switch in a moment. So, you can say that the functionality of these units is quite simple yet extremely important.
When this action happens, the internal strip of the unit produces a clicking sound. You can adjust the external force that can activate the switch. In other words, you can decide on how much pressure needs to be applied in order to make the switch work.
Although these micro switches have a simple design, it is the quick response of the unit that makes it an ideal choice for a variety of applications in the here and now. Therefore, these products have replaced a lot of other products that were introduced earlier. So, I can say that these switches run circles around a lot of other units you can find in the market.
So, this was an introduction to how these microswitches work and what you can expect from them. If you want to get the most out of them, we suggest that you buy them from a good company. After all, you don’t want to end up with the wrong unit. Therefore, choosing the best unit is a stroke of genius.
