Different Types Of Micro Switches

Different Types Of Micro Switches

There are many different types of micro switches. According to volume, hundreds of internal structures, primary, mini, and subminiature.

  1. according to protection performance, there are waterproof types, dustproof types, and explosion-proof types;
  2. according to the kind of breaking, there are the single connection type, double multiple connection types; 

    There is also a strong disconnection microswitch (when the reed of the switch does not work, the external force can also make the button open)

   1. according to the breaking capacity, there are ordinary type, DC type, microcurrent type, and sizeable current type.

   2. According to the use environment, there are ordinary types, high-temperature resistant types (250℃), and ultra-high temperature resistant ceramic types (400℃). The micro switch is generally based on the non-auxiliary pressing attachment as the primary type and derives small and large stroke types. According to needs, we can add different auxiliary pressing accessories

The switches can be divided into various types: button type, reed roller type, roller lever type, short lever type, long lever type, and so on, according to the different pressing accessories added.


Micro Switch Application

They use microswitches for automatic control and safety protection in equipment requiring frequent circuit replacement. And they widely use microswitch in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, aerospace, aviation, ships, and missiles. Such tanks have been widely used in the above areas. 


Micro Switch Service Life

Although the switch is small, it plays an irreplaceable role. The micro-switches on the domestic market vary from 3W times to 1000W times according to different requirements. Generally, 10W, 20W, 50W, 100W times, 300W times, 500W times, 800W times, domestic general use Beryllium bronze, tin bronze, and the switch uses stainless steel wire as reeds.

Microswitches are electrical switches designed with an actuator and standard terminals, normally open and closed.

A microswitch is also known as a snap action switch. They operate by using a spring-loaded lever to open and close a set of internal contacts inside the unit.


How does a microswitch work?

Power is typically attached to the common terminal, which leads into the switch and energizes the spring. Because the spring is touching the usually closed pin, it sends power out here, called a resting state. Once the application moves the arm, the switch transfers the emphasis to the normally open pin.


Where would you find them?

Their electrical characteristics differentiated Microswitches. These are small devices and are generally only designed to carry low currents and voltages. People commonly employ these switches as safety devices. They are reliable, inexpensive, and can open up a circuit when needed, preventing a machine from turning on or closing a door when someone is in the way.


Actuator types

There are various types available, but the operating principles are the same, people actuated the switches by a plunger, a button, a roller, or a lever.


What is their working Life?

Microswitches’ operating Life is generally very high. People measure results in millions of cycles in most cases. Consumer products have lighter-duty microswitches than industrial products typically. Still, the low cost of these parts makes it easy enough to upgrade to higher mechanical life expectancies when required or when it’s simply beneficial.



We offer a range of high-quality sealed miniature and sub-miniature microswitches that meet industry standards and RoHS compliance. 


What type of applications need microswitches?

People use microswitches in consumer devices and industrial equipment. Typical applications for these devices are indoor interlocks, microwave ovens, or where a door has to be shut before the power to the device will turn on. Microswitches are also used in leveling devices, such as vending machines. These devices are used in the door as a safety switch in an elevator.

Microswitches can be designed to be very sensitive. People can use their design equipment to measure airflow or other gasses through a system. These devices are used extensively in industry, often in control circuits.
