Micro switches exist widely in people's daily life, but if you really want to tell the details of it, and accurately answer what a micro switch is, many people are still confused. Today, I will tell you what a micro switch is.
1. What Is A Micro Switch
The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism, which is a contact mechanism that uses the external force and the elastic force of the internal shrapnel to perform the switching action with a specified stroke and a specified force. , Because the contact distance of the switch is relatively small, it is called a micro switch, also called a sensitive switch. It is widely used in program conversion of FLECK control valve and control solenoid valve, pump, and other devices.
2. Different Types Of Micro Switches
There are many types of micro switches, 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, and multi-link types. 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, and high-current type. According to the use environment, there are ordinary types, high-temperature resistant types (250℃), and super high-temperature resistant ceramic types (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. In terms of size, there are small, ultra-small, ultra-small, and so on. Functionally, it is waterproof. The most common application is the mouse button.
