Micro switches are electrical switches and can be started with very little force using a turning point mechanism. These are also popularly known as miniature snap action switches.

There are about 19 types of microswitches that are used in different mechanisms. A micro switch reacts to the environment and gives a quick reaction accordingly. When a microswitch detects a change in the environment around it, its piston is pressed or released. They are capable of making instant changes with very little force. A small force, such as a slight change in the environment, acts as a stimulus and activates the piston actuator inside.

Micro switches come in variable sizes and shapes, such as small and super small sizes. The position of a switch is undoubtedly irreplaceable. From home appliances to military mechanics, micro switches can be found everywhere.

Just as these can be found in different categories, the actuators present in them are also variable and are of a few different types.

Types of actuators:

• blade actuator
• mustache actuator
• Styrene float actuator
• roller actuator
• Sail or oar actuator

Uses of Microswitches

Microswitches are installed in various mechanisms. They are mainly used in printers to detect paper jams. They are also used for leveling and safety purposes in elevators.

Micro switches are a common component used as industrial equipment in automobile machinery and other home appliances, such as in a microwave door interlock system.

Control systems, lamps, solenoids are also equipped with these switches. They are also used to detect whether a valve in a fire sprinkler system is open or closed as a tamper switch.

Some microswitches are specialized to detect coins going into a vending machine. These microswitches are also sometimes equipped with paddles to help you detect airflow.

Factors such as temperature, airflow, and ambient pressure can trigger a microswitch.

Micro switches can also be used as a timing mechanism. These can also be used as electrically powered machine tools in instrumentation, power systems, and home appliances. They are also used in large machines and systems such as aviation, missiles, tanks, etc.

Benefits of Micro Switches

Microswitches are used very often due to their reliability. These switches work continuously in response to their environment. Since these switches are used as a safety mechanism, they must be reliable.

These switches are very durable. Even lost cost switches can run millions of rounds, and if you buy an expensive microswitch they can run 10 million cycles. The designs of these switches naturally make them durable.

If you buy them in bulk, you can get a very good deal. With its reliability and durability, it is a very attractive offer. All these reasons make microswitches a widely used component in simple and complex machinery.

These microswitches work very quickly, which makes them reliable enough to be used in security mechanisms. From simple to complex mechanisms, micro switches are used everywhere due to their durable nature.
