Classification of microswitches
According to the volume classification, there are small, ordinary, ultra-small micro switch, different volumes of micro switch wiring methods are also different. If it is divided according to the protection, there are waterproof, anti-riot, dust-proof, etc., according to the form of breaking to be divided into double type, single type, multiple type, etc., there is also a strong disconnection of the micro switch.
How Micro switches Work
Micro switches are used to control the circuit switching by operation. When the micro switch comes in closed state, a closed circuit will be made between the static and dynamic contacts and the current can flow out through the microswitch. When the microswitch comes in the open state, a circuit will be broken between the static and dynamic contacts and the current will be cut off.
The principle of micro witch
In the micro switch, its rotating elements have buttons, push pins, rollers and levers, etc., as long as the external mechanical force, through the rotation of the elements, the force acted on the spring sheet, when the reed is shifted to the critical point, resulting in instantaneous action, so that the reed can touch the contact, so as to achieve disconnection and rapid on.
Introduction of Micro Switch
A micro switch is a common electronic component. It consists of three parts: a contact part, an operating part and a cover part. It is to control the circuit switch by manual. Owing to its simple structure, easy installation and use, high reliability and other characteristics, micro switch is commonly applied in various electrical equipments.
Frequently Asked Question
Do you have any question?
Invented in 1932, Micro Switch is a world-renowned technology that still works today. Their strength, repeatability, reliability, high current capacity, and small size or weight make micro-switching devices an ideal and cost-effective solution for many of today's modern machines and appliances.
Switch endurance refers to the situation when a switch operates at a specified frequency and at a specified overrange (OT) at a rated load. Micro switches are not user-maintainable, but they should be kept fairly clean, paint-free, especially in the actuator area.
Our switch quality is guaranteed, the price is the factory price, no middlemen, good quality, good price.
Express delivery/Forwarder, depends on customer's requirement.
Yes, we have patent for micro switch.
