Common on the marketmini switch, The size may be only a few millimeters, or about one centimeter, with different metal feet, such as flat feet, plug-in type, three feet, four feet, six feet, seven feet, etc. Many even have different styles of metal feet. Mini switches are mostly made of metal or plastic, and some have gears, which can be used in different electronic products, and they are very cheap, so they are very popular with buyers. Another advantage of this switch is that it is very durable, that is, it is suitable for both electronic products and low-end products. Although the mini switch is small in size, the quality is not inferior to the normal size switch, or even better.

The four key points of the mini switch are as follows:

1. It is very important to understand how the external dimensions of the mini switch affect the choice of other characteristics. The size of the mini switch should be based on the purpose of the product, as well as the design of the product size and internal space size. Engineers need to design the position, placement, space, handle strength and other important parameters of the mini switch before development.

2. The mini switch can generally disconnect the voltage and current from 5MA/5VDC to 25A/380VAC. Mini switch has the advantages of low power consumption, high reliability and low cost. The tact switch product line provides users with low-energy power load electrical series, suitable for various products. In practical applications, switches can be used in low-voltage systems or high-impedance systems, but evaluation and design are a challenge. In addition to the load requirements, the engineer must also select the appropriate circuit. There are two types of switch contacts, normally open and normally closed, both of which are normally open contacts. In general, no current flows between the contacts. When on or off, the contacts are closed or separated to realize power conversion and output control functions. When the switch operates, the contact is closed and the line is connected. If it is necessary to protect the circuit when it is opened and closed, a special design should be adopted. For normally closed contacts, in general, a current will flow between the contacts. When the switch acts, the contacts will open and the circuit will be cut off.

3. Ambient temperature conditions. The choice of mini switch is greatly influenced by environmental requirements, such as industrial control. In critical applications that require high reliability, such as medical equipment, the environmental conditions are composed of air humidity, and industrial requirements such as temperature are put forward for harsh environmental conditions. The sealed waterproof switch needs to choose a wide temperature range, the protection level should reach below IP67, and the optional working temperature range is -40 degrees to 150 degrees.

4. Whether the switch is reliable is very important. It is necessary to clearly understand how many times an application uses electricity, mechanical life, switches, contacts, different materials, housings, and terminal life. In the switch industry, it is the mechanical life that is important. A long-life mechanical switch can reach more than 10 million times, and the electrical life can also be injured 1 million times. For mini switches, the price is different and the quality requirements are different. You should consider the total cost of use and confirm which suitable mini switch to use.
