A28KW Toggle Switches Application Field and Working Principle

A28KW toggle switches are a kind of common switching devices. They are widely used in various electrical and electronic circuits to control, power, image and sound signals. The purpose of this article is to introduce the application field and working principle of A28KW toggle switches.

Application Field of A28KW Toggle Switches

A28KW toggle switches are made of zinc alloy and the core elements are switches. They are mainly used in the control circuit, working current 5A/125V, operating temperature -25℃ to 55℃, no fire resistance and pollution. The main application field of A28KW toggle switches includes the following:1. Automotive Electrical Systems: Toggle switches can be used for switches, controlling the circuit of automotive electrical systems, electrical control devices and instruments, such as car radios, car lights, car ignitions, and various instruments and indicators in automotive electrical systems.2. Household Appliances: A28KW toggle switches are used in various household appliances, such as air conditioners, refrigerators, washing machines, microwave ovens, rice cookers, coffee makers and other electrical appliances. 3. Industrial Equipment: Toggle switches are also used in various industrial equipment, such as cranes, elevators, metallurgical equipment, machine tools, woodworking machinery and other industrial machinery and equipment.

Working Principle of A28KW Toggle Switches

A28KW toggle switches are switching devices that connect and disconnect a circuit. The toggle switches of this type are connected/disconnected by pressing the rocker switch on the toggle switch. The rocker of a toggle switch is usually composed of a dielectric material and a bouncing steel sheet. The dielectric material acts as an insulation protection for the bouncing steel sheet. A contact is arranged at the end of the bouncing steel sheet to control its action. When no external force is applied, the bouncing steel sheet is in an unstable position in the middle, and the contacts at both ends of the bouncing steel sheet are out of contact. When the toggle switch is pressed, the lower end of the bouncing steel sheet is pressed, and under the action of elastic deformation, the bouncing steel sheet jumps up and the contacts at both ends are connected, thus completing the switching action. When released, the toggle switch is disconnected. The bouncing steel sheet relaxes due to its own elasticity, and the contacts at both ends of the bouncing steel sheet are disconnected. Thus, the circuit is disconnected and enters the original state. The operating force of the toggle switch should be appropriate, too large or too small will affect its switching effect. In conclusion, A28KW toggle switches are widely used in various electrical and electronic circuits. Upon pressing their rocker switch, the circuit will be connected and disconnected.
