Pushbutton switches have been a mainstay in industrial applications for a long time. While pushbuttons are primarily used to control a single device, there are also applications that require multiple, or even hundreds of devices to be controlled simultaneously. To address this need, manufacturers have designed special pushbuttons that can be used in multiple applications. One type of switch, the SB25-BA, is especially useful in such applications due to its ability to be adapted to a wide variety of uses. This article will discuss the application field and working principle of the SB25-BA pushbutton switch.

Application Field

The SB25-BA is a two-pole, two wire pushbutton switch that can be used in a variety of applications. It has a compact design and is typically waterproof, making it ideal for outdoor use. Furthermore, the switch features a robust construction and is able to withstand the extreme temperatures and conditions found in industrial settings.

The SB25-BA can be used to control circuits with low or medium current, as well as circuits with pulsed loads. It is also capable of communicating with microprocessors, as it is equipped with a built-in transistor. This allows the switch to send signals to and receive signals from the processor.

The switch can be used to control a wide range of devices, including electrical motors, lights, and valves. It can also be used to control pumps, compressors, conveyors, and other industrial machinery.

Working Principle

The SB25-BA employs a “two-pole two wire” system for its operation. This means that it uses two wires to control two separate electrical circuits or devices. The switch is normally closed and is activated when the button is pushed. The activation of the switch causes a “break” in the circuit, which cuts off power to the device or circuit that was previously connected.

The two wires that connect to the switch carry two different voltages. One wire carries a high voltage, and the other wire carries a low voltage. When the button is pushed, the high voltage is cut off, causing the circuit to break. When the button is released, the low voltage is restored, allowing the device or circuit to be powered again.

The SB25-BA utilizes a locking mechanism for safety. When the button is pushed, the locking mechanism is activated, preventing it from being released accidentally. This provides an additional layer of security and ensures that the switch will not be triggered unintentionally.

Conclusion

The SB25-BA is a versatile and reliable pushbutton switch that can be used in a variety of applications. It is highly adaptive and can be used to control circuits with low or medium current, as well as circuits with pulsed loads. Furthermore, its robust construction and waterproof design allows it to be used in extreme conditions. Finally, its locking mechanism provides an additional layer of safety, ensuring the switch will not be activated inadvertently.
