Microswitches, also known as miniature snap action switches, were developed by Peter McGall in 1932. 5 years later, he founded the Micro Switch Company. Approximately 13 years later, Honeywell bought this company. Micro Switch is a trademark, but the term began to be used commonly for all similar products. Let’s find out more about the design and the many uses of these units.

How does this unit work?

These units are basically activated even if minimal force is applied. There is a trigger mechanism behind its functionality. There are three contacts on the switch. They are called Common, Normally Closed and Normally Open. Depending on the design of the unit, you can allow or stop the flow of current. The floor will resume only when the mechanism is activated.

In the case of a normally open unit, current flow is not allowed until the closed position is achieved. With the normally closed switch, electricity is allowed to flow until the switch ends the flow.

What are these units used for?

Microswitches have numerous uses despite the fact that these units are quite small and cheaper to manufacture. They are typically used in electrical circuits, door locking mechanisms, and many other household appliances. Hence, a microswitch is one of the most widely used components these days.

Apart from this, they are commonly used in the security mechanisms of different types of Elevators. They can also be found on copiers for detecting jammed paper. They are also an important component in home security systems.

The mechanism of the window or door activates the switch, which triggers the alarm. They are equally useful in different types of fire safety systems. Also, they are used in vending machines these days. Many manufacturers use microswitches to identify blockage on a production line. For example, they are used to stop belt movement so engineers have enough time to solve the problem.

You can choose between different types of microswitches depending on the type of application. Therefore, we suggest that you consider the style and size of the unit based on the job you want to use them for. For example, some of the units are designed for easy use. On the other hand, some of the units are specially designed for specific purposes.

We suggest that you check the performance and health of the product to make sure the mechanism is operational. If the unit is damaged, you may want to replace it immediately to ensure the safety of your appliances and security systems.

Simply put, this was an introduction to microswitches and their applications. If you are looking to buy these switches, we suggest that you follow the advice given in this article. This will help you get the best unit for your needs. After all, you don’t want to end up buying the wrong unit.
