The technical term for micro switches is a miniature step-action switch. This is a type of electrical switch that gets actuated through minimal force. These units use a tipping-point mechanism. In this article, we are going to know more about the uses of these units. We will also know about some advantages that these devices offer. Read on to find out more about it.
What are they made from?
Basically, these devices are made from metal strips and a spring. If the switch button is pressed, the spring flips causing the device to activate. The metal strip goes back into the original position when the pressure is lifted. The set of metal makes a clicking sound when it is pressed. This sound is similar to the sound produced by your computer mouse when you click the buttons. Typically, the size of these switches is 3mm x 3mm x 9mm.
The Advantages of Micro Switches
First of all, these units are quite reliable. Their operation is quite reliable unlike other types of units you can find out there. Since they are used in safety mechanisms, they must be quite reliable. Durability is another great advantage of these tiny devices.
Even if you get a basic unit, it can go beyond one million cycles before replacement. On the other hand, high-end units can be good for 10 million cycles. They are designed in a way that they can last several years.
Another great advantage of these units is that they are quite inexpensive, especially if you place a bulk order. This is the reason they can be found in almost all electronic markets. As a matter of fact, micro switches are on the list of the most commonly used electronic components.
The Application of Micro Switches
Micro switches are used in a lot of appliances and office products. For example, you can find them in winters, vending machines, microwave oven, door interlocks, and millions of safety devices. Besides, they can also be used to detect the opening or closing of a valve. For example, they perform this function in fire sprinkler systems.
Apart from this, they can be found in a lot of domestic appliances, industrial equipment and different types of vehicles. They are also used in different types of control circuits in order to control electric motors, solenoids, and lamps, just to name a few.
A sensitive type of micro switch is used in vending machines to sense the dropping of coins. These units can be operated using a certain mechanism.
Micro switches also work as a timer mechanism. They are also used with leavers, plungers, and rollers. The role of micro switches in these systems is to control machine tools or machinery.
Long story short, this was an introduction to micro switches, their uses, and some benefits they offer. If you are looking for a unit for your personal or business purpose, we suggest that you take your time and buy from a supplier that you can depend on. Hope this helps.
