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.
