1） the size is small but can switch large current
Normally, when an electronic circuit is turned off, sparks called arcs are produced between the contacts. The higher the current is, the more likely it is to produce arc light, the slower the switching speed of the contact and the longer the duration of arc light, which are the factors leading to the deterioration of the contact. The quick mechanism of microswitch can switch contacts instantly, so the arc light lasts for a short time and can be used in circuits with large current although the size is small.
2) High precision
Microswitch can switch contacts in the same position even if repeated open/close operation, so the position detection error is small, suitable for high-precision applications. This is also the unique advantage of microswitch with quick mechanism
3) Durability
Due to the short arc light duration, the contact is less damaged, so the durability is improved.
4) Touch and sound
The quick-acting mechanism has a unique touch and sound during operation, so the operation can be confirmed by touch and hearing.

Micro switch, it can use very small force can open the switch, and the distance between the contacts is relatively small, torque is relatively large. Generally speaking, the size is divided into small and super small, there is a super small. Customers can look at the size of the switch they need to buy according to the specific situation, we use a lot of mouse buttons in daily life, is the role of the micro switch, so the installation and use of this switch need what kind of environmental guarantee?
When welding the microswitch manually, try to choose a temperature lower than 320℃, and can ensure that the configuration can be completed within three seconds. At the same time, it should be noted that when working, do not put pressure on the terminal, otherwise the equipment may not work properly. If the switch is used on a relatively small current or voltage, it is best to use a low-power circuit, that is, Au cladding contacts. At the same time, when the switch is in use, attention should be paid to waterproof, and the temperature should also be within the specified range. Only when all the above conditions are met, can this kind of switch give full play to its maximum power and ensure the normal operation of the equipment. Only in this way can the service life of the switch be extended.
