What are the types and models of micro switches?

Micro switches come in a wide range of types and models, allowing you to choose the right type and size of switch for your specific application. When choosing a micro switch, you usually need to consider factors such as the size of the switch, its mode of operation, electrical characteristics, and protection level. In this article, we focus on the types and uses of micro switches so that you can make a reference when selecting a micro switch for your project.

Micro switches, as the name suggests, are electronic switches that are mini in size and operate with very little effort. Its main structures are: contacts, terminals, levers, brackets, movable tabs, push buttons, and form-actuated arms. Micro switch contact spacing is small, short action stroke, press the power of small, on and off quickly, also known as sensitive switch.

Its working principle is the external mechanical force through the transmission element (pin, button, lever, roller, etc.) will be applied to the action of the reed, when the action of the reed displacement to the critical point of the instantaneous action, so that the action of the reed end of the movable contact and the fixed contact quickly connected or disconnected.

There are hundreds of types and styles of micro switches, which can be categorized according to the following aspects.

1. Size

micro switches are categorized by their size, including basic, small and ultra-small.

With the advantages of miniature size and not occupying too much internal space, micro switches are successfully used in household appliances, automotive industry, electronic equipment, communication equipment, medical equipment and other fields.

2. Protection Performance

micro switches are categorized in terms of protection performance, including waterproof, dustproof and explosion-proof.

Because the application environment of micro switches is variable, often to be used in high humidity, dust, high temperature and other harsh environments, so to ensure that the electrical performance of the micro switch is not affected, its protection is very necessary.

3. Breaking form

micro switches are categorized in terms of breaking forms, including single-connection, double-connection and multi-connection types. In many applications, micro switches no longer control only a single circuit, but can be selected according to the number of circuits they wish to control.

4. Breaking capacity

micro switches are categorized in terms of breaking capacity and are available in ordinary, DC, micro current and high current types. In different application fields, the required current size is also different.

Some micro switches are only used for signaling and require very small currents; some micro switches are used in some high-power electronic equipment and require high currents. Therefore, when selecting a micro switch for your product, you should first determine the actual current to be used.

5. Environment

micro switches are categorized in terms of the environment in which they are used, and there are ordinary types, high-temperature-resistant types (250°C) and ultra-high-temperature-resistant ceramic (400°C) types.

Micro switches have a wide range of uses despite their miniature size. From the household appliances around us, such as rice cookers, air fryers, kettles, dishwashers, electric fans, heaters, etc., to the automotive industry, such as automotive door lock switches, engine locks, trunk, reading lights, gear shifters, charging piles, charging guns and so on.

All these places are not without the role of micro switches. It can also be used in various products such as rechargeable treasure, shared bicycle, express cabinet lock, vending machine, ETC, brake switch, security system, industrial equipment, medical equipment, communication equipment and so on.

All in all, micro switches are actually not strange to us, they can be found everywhere, which bring us a lot of convenience and enhance the life experience. If you are interested in micro switches, welcome to visit Yongxing official website for more details!
