In life, we will find that many products are very sensitive, and can be opened or used with only a light touch. This is all thanks to the #microswitch inside, which can be controlled with a slight touch. achieve the effect of the switch. Therefore, most of these types of switches are used in door locks in anti-theft systems or other household appliances or electronic devices. The product itself is dustproof and waterproof.

Micro switch: As the name implies, it is a switch that uses very small movements (forces) to execute instructions. It can be made into a volume smaller than a soybean grain, and is mostly used in occasions with low current, such as buttons on mobile phones. (a film) The switches under the left and right buttons of the mouse, of course, the micro switches are very large or even tens of millimeters in size, and the current it controls is large, but its stroke is very small, so they are still micro switches. The category of switches!

There are many types of #microswitches, and there are hundreds of internal structures. According to the volume, there are ordinary, small, and ultra-small; according to the protection performance, there are waterproof, dust-proof, and explosion-proof types; Single type, double type, multi-link type. At present, there is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect); according to the breaking capacity, there are ordinary type, DC type, micro-current type, high-current type . According to the use environment, there are ordinary type, high temperature resistant type (250℃), super high temperature resistant ceramic type (400℃)

Micro switches are generally based on unassisted pressing accessories as the basic type, and small stroke types and large stroke types are derived. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switches can be divided into various forms such as button type, reed roller type, lever roller type, short boom type, long boom type and so on.

#Microswitches are used for automatic control and safety protection in equipment that requires frequent circuit switching, and are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, Military fields such as tanks have been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.

A micro switch is a pressure-driven quick switch, also known as a sensitive switch.

The working principle of the micro switch is:

The external mechanical force acts on the action reed through the transmission element (pressing needle, button, lever, roller, etc.), and after the energy accumulates to the critical point, an instantaneous action is generated to move the reed that has finished the action. Contacts and fixed contacts are quickly connected or disconnected. When the force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantly.

Advantages of micro switches:

#Micro switch has small contact distance, short action stroke, small pressing force and fast on-off. The action speed of the moving contact has nothing to do with the action speed of the transmission element.

Classification of micro switches:

The micro switch is based on the push-button type, and can be derived from the button short stroke type, the button long stroke type, the button extra stroke type, the roller button type, the reed roller type, the lever roller type, the short arm type and the long arm type. There are a lot more. Micro switches are used in electronic equipment and other automatic control and safety protection devices that require frequent switching of circuits. Micro switches are divided into large, medium and small. According to different needs, it can be divided into waterproof type (for liquid environment) and ordinary type.

Application of micro switch:

This switch connects two circuits and provides on-off control for appliances, machines, etc. Widely used in mouse, household appliances, industrial machinery, motorcycles and other places. Although the switch is small, it plays an irreplaceable role.
