The Macro World of Micro Switches


The word micro does ring a bell of being small, right? But it is this micro system that does wonders in the electrical world. Big miracles often tend to happen through small people, just like the story of Goliath. Right from automation until security, they have a wide range of uses.

Micro industry

The micro switches, as the name suggests, are small switches that are used in bell systems or in small parts of a computer chip. Most of these have a plastic coating guided along with a metal in the back for conducting electricity. Other switches, for example, the ones that we use in our homes like fans or lights, are just one way. We either switch it on or we switch it off. The whole world drives in automation right now (having Alexa and automated cars like the Tesla) and these are a major part of this automation industry. They are used in the manufacturing of alarms for households, in surveillance cameras, in elevator switches, in timer bombs and many more. So, in short, these can be referred to as devices that are helpful in the safety industry and are the perfect design.

Useful application

Not only do they ring a bell and protect our homes, but they are also utilized in our daily uses like machines, refrigerators, AC’s, etc. They have a simple lever mechanism which helps them glide back into their normal state after being pushed just like the doorbells or alarm systems. In short, they depend highly on the input given, unless, otherwise, they stay stable in their own position. This could also be better explained by using Newton’s third law which states the system stays at rest unless an external force acts upon it.


No other category of switches has this lever uniqueness, going back to their own form after being pushed. The usual switches are just the form of either on or off. These tend to disobey the master and have their own rules!

Recent trends

As small is the new big, people are more focused towards creating a nanotechnology world. These switches prove to be the right platform. They are engineered in such a way that they can literally fit into any electronic gadget and provide the same purpose. They are extensively used in alarm systems and triggers. They are also recently being employed as one of the substitutes in cars in the accelerators and clutches. The design is being modified in order to fit into any system.


In the micro-environment era, these switches are in high demand and prove to be most effective in terms of both manufacturers as well as buyers. With engineering being improved to the level of having a lens in sight, these micro switches tend to bring out the new in every aspect and prove to be highly efficient.

Unionwell is the most famous and trusted among all the China microswitch manufacturers.


A microswitch is a switch that responds to all the changes in the surrounding environment by closing or opening a series of switches that are used to hold back the device.

Switch Applications

Microswitches are common devices which are mostly used in various consumer devices, industrial plants and many other places. The most common use of these devices is the door locks; these are essential in microwaves where the door has to be closed before the oven is switched on. Leveling devices such as vending machines also use microswitches. In elevators, microswitches are used as the safety switches. They are also used to check or detect whether a paper is jammed in the copier. These microswitches are very sensitive. They are used to measure the air flow or the flow of gases in any system. These switches can also be used to accurately measure temperature and pressure. These efficient switches are also used in various industries, often in the control units; these devices are also used as the direct means of switching any device on and off.

User Input

User input is considered to be the most common use for switches, e.g. if a person needs to connect any switch to a micro controller input.

Some Concepts of Switches

Transistors: These are mainly used as the electronically controlled switches.
Pull-Up Resistors: These usually complement the current button circles. They make sure that the ground and current are not fully short circuited. They also make sure that the input and output lines do not float.
Motion sensor accelerometers: These switches are mainly used in video game controllers and smart phones; these are faster and more efficient than normal switches.
Relay: This is another switch that is electronically controlled; it is best for high-performance circuits.

True Agility Starts With Collaboration

Organizational design and business agility has always been an area of interest to me, long before they were buzz terms. I enjoy assessing the people and goals of organizations and analyzing the psychology behind it all. In 2007, I completed my first formal agile training and certification (Scrum Master). This program was energizing and inspiring, not just for the learning aspect, but because of the way agile can transform our working lives. Immediately following the course, I found opportunities to utilize the approaches discussed, including implementing Scrum for eLearning course development. While the organizations I supported were not always ready for true agility, I hung on to the overarching theme and message behind agile.

Many people have written and expressed frustration on what agile is not. For those who see the power in agile, you will also see that agile is not a tool, it is not turning requirements into user stories, it is not packaging agile as a daily standup (where everyone sits due to the length) and it is not being a development focused business. Agile is focused on value creation. And at the heart of agile is how value is created. Many individuals in organizations think that their independent work creates value. In many cases these individuals are creating value, but all too often, they operate in isolated, disconnected work streams and are creating their personal version of value. It goes back to what the customer is willing to pay for, what will move your organization to the next level and developing organizational momentum that is in lock-step with the customer. Many organizations even go so far as to say they are agile or collaborative. Do we really understand what it means to collaborate? I believe this is at the heart of it all.

If we understand and practice collaboration, we will be in tune with customer needs/changes and be so closely aligned that we are one step ahead of the what our work should deliver. The agile manifesto also talks about interactions over processes and tools, working software over documentation, and responding to change over following a plan. I feel all of these can be achieved through true collaboration and alignment. To fully collaborate, I believe the following pre-conditions need to be met:

Individuals need to leave biases at the door
Individuals need to be able to communicate expectations
Individuals need to be committed to keeping their promises
Individuals need to be self-aware and able to give fully to the team
Individuals need to be committed to the success of the team and organization overall, letting go of personal competitive needs
Individuals need to be respectful not only to new ideas, but to other individuals at large

Here are my top 10 ways on how to foster collaboration and create a culture that is ready to be agile:

Be present for team members
Practice active listening
Create safe spaces that allow team members to grow together and individually
Be accountable to the team
Avoid blaming others for misses
Be patient and generous with your time
Ask for help
Share credit
Challenge the work being done to ensure it is essential
Appreciate team members and communicate their value

I am a strong believer in changing the way we approach work and perform work for optimal individual and organization growth. Perhaps this is why many agile transformations start, but fizzle out or end up being a waterfall-like process branded as agile. The old adage, “nothing worth having is ever easy” comes into play here. To move yourself and organization to operating with agility, requires more of a cultural shift than ever before.
