SET BU AU OA

Pushbutton switches are an important type of switch which is widely used in industrial and consumer electronics. These switches are designed to operate at a certain voltage and specify a certain operation when they are pressed. The most common types of pushbutton switches are SET, BU, AU, and OA. In this article, we will discuss the application field and working principles of each one in detail.

SET switches are commonly used in appliances such as power tools and fan controllers. They are designed to turn a circuit on and off. When pressed, the switch will connect the two terminals and provide power to the circuit. When the switch is released, it will break the circuit and the power will be removed. SET switches have a long life cycle and can be used for up to 25 million cycles.

BU switches are typically used as an on-off switch in consumer electronics, such as TVs and stereos. They are designed to cycle between the two terminals and can be used to control volume and power. BU switches usually feature a spring-loaded button which will snap back to the center position when released. These switches are designed to last up to 100 million cycles.

AU switches are designed for specific industrial purposes. They are commonly used to control the speed of conveyor belts and other mechanical equipment. When the switch is pressed, the circuit will connect the two terminals and allow power to flow to the equipment. These switches can be used for up to 50 million cycles.

OA switches are generally used as an input device in industrial automation systems. They are designed to detect the presence of a signal and then change the state of the circuit. They are commonly used to detect when a lever is in the open or closed position. OA switches have a long life cycle and can be used for up to 100 million cycles.

In conclusion, pushbutton switches are an essential component in a wide variety of products. Different types of switches have different applications and have varying lifespans. SET, BU, AU, and OA switches are each designed for specific purposes and offer different levels of durability.
