Toggle switches are widely used in various applications, such as power electrical equipment, audio equipment, computers, and other electronic machines. The B25AP is one of the most commonly used toggle switches for its ease of maintenance, stability and good price. Here, we will discuss the application field and working principle of B25AP.

B25AP is a type of 2-pole, 2-position toggle switch. It is usually made of copper alloy, silver alloy, nickel plating, and other high-grade materials, which results in decent overload, wear and corrosion resistance. Therefore, B25AP is very suitable for use in the power systems, with the electricity up to 16A. Furthermore, the lightweight, small sizes of the switch make it ideal for the home electrical appliances, such as lamps, air conditioners and so on. Besides, due to its convenience and security, it also can be used in some medical devices, high temperature and low-cold working environment equipments, communications, aerospace and more.

As for the working principle, B25AP is a manual control switch, meaning the power will only be switched-on when the operator manually presses or pulls the lever or button. The switch itself is composed of several major components including an actuator, a contact pair, spring, terminal, and housing. When the switch is on, the terminals will be connected as the contact pair is bridged. When the switch is off, the contacts are separated, so that the power will be cut off.

Generally, the actuator is shaped like a lever, and a rotating eccentric cam is used to drive the contact among up, down, right and left so that freely switches the circuit by an operation. After the operator presses or pulls the lever to the desired state, a pivotal axis is moved, which is acted upon by the spring and the contact is moved to make contact with another contact. And this initiates the conduction and makes the circuit complete.

In conclusion, the B25AP is a safe, reliable and cost-effective toggle switch, which can be used in a wide variety of application fields. It features a manual control system and contacts are moved to make contact with one another when the switch is initiated. Therefore, it is ideal for a range of connection systems in the power system.
