The micro switch is one of many switches. It's just that the contact distance of the switch is relatively small, so it is named "micro switch".
So what types of switches are there? What matters should be paid attention to when using?
There are many types of micro switches, and there are hundreds of internal structures. The classification of micro switches is analyzed in detail. The details are as follows:
1. According to the volume, there are ordinary, small and ultra-small;
2. According to the breaking type, there are single type, double type and multi-connection type;
3. According to the protection performance, there are waterproof type, dustproof type and explosion-proof type;
4. According to the breaking capacity, normally open, normally closed, and normally open and normally closed conversion type;
5. According to the use environment, there are ordinary type, high temperature resistant type, super high temperature resistant ceramic type;
The basic type of the micro switch is generally without auxiliary pressing attachment, and the small stroke type and the large stroke type are derived. Different auxiliary pressing accessories can be added according to needs, such as flat pressing rods, roller pressing rods, and special-shaped pressing rods. To meet the needs of our customers, our company can customize them according to customer needs.

Precautions for using Tongda WEIPENG micro switch
1. Please select the appropriate type of switch according to the requirements of rated current, operating load, drive rod type, operating temperature and other requirements;
2. Please choose a sealed switch in an environment with high humidity, impurities and dust.
3. Please do not add oil to the button and drive parts, otherwise it may cause abnormal switch function or even burn. When in use, force should be applied in the vertical direction corresponding to the button.
4. Please install the switch on a flat surface and fasten it with flat washers or spring washers. If the mounting surface is uneven, it will cause the switch to fail or be damaged. If using screws for fixing, place small screws on a smooth surface with a torque of 0.098N•m or less. In addition, in order to prevent the screws from loosening, it is best to use washers under the screws.
5. Switch storage environment: The product should be stored in a warehouse where there is no rain and snow, air circulation, drying temperature of 0 ℃ ~ 55 ℃, no harmful media, the number of stacked layers is not more than 5, and sealed storage.
Switch application range:
Widely used in various household appliances, medical equipment, military industry, electronic equipment, automation equipment, communication equipment, automotive electronics, power tools and other fields.
