DONGNAN ELECTRONICS CO.,LTD established in 1987, with more than 30 years manufacturing experience in making switches. Mainly produce micro switches, water proof micro switches, power switches, gate control switches, rotary switches, voltage-selected switches etc. We are a national-level new and high-tech switch manufacturing enterprise that has R&D, producing, marketing and after-sales service, and our switches are widely used in whole China and oversea countries.
The opening point, closing point and common point that must be in a switch are inevitable, and the components that rotate the switch, such as buttons, levers, springboards, brackets, electrical contacts, reeds, etc., are also necessary in the structure of the micro switch.
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.
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.
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.
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.
