What is a micro switch

Share This Post

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 quick switch actuated by pressure, also known as a sensitive switch. Its working principle is: the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, an instantaneous action is generated, which makes the end of the action reed move. The contact and the fixed contact 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 instantaneously. The contact distance of the #microswitch is small, the action stroke is short, the pressing power is small, and the on-off is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element. The micro switch is based on the push pin type, and can be derived from the button short stroke type, the button long stroke type, the button extra large stroke type, the roller button type, the reed roller type, the lever roller type, the short boom type, and the long boom type. and many more. Micro switches are used in electronic equipment and other equipment for 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, they can be divided into waterproof type (used in liquid environment) and ordinary type. The switch connects two circuits to provide on-off control for electrical appliances, machines, etc. It is widely used in mouse, household appliances, industrial machinery, motorcycles and other places. Although the switch is small, it plays an irreplaceable role.
