AOLD3QH211DNUW

The AOLD3QH211DNUW is an electromagnetic pushbutton switch, usually referred to as a pushbutton. It is part of a family of electrically operated switches and devices primarily used to switch electrical contacts. Commonly used in industrial and consumer applications, pushbutton switches are durable, versatile, and offer various mounting, size, and actuator options.

Application Field

Pushbutton switches are used in numerous applications, ranging from consumer products to industrial automation control. Pushbutton switches are used in consumer products such as radios, TV\'s, and other household gadgets. As well as consumer products, they are used in industrial applications and machine control. They can be used as momentary or latching switches, and are available in different sizes and shapes, standard or sealed, and with many different types of actuators.

In industrial environments, pushbutton switches are used to control machines, automated processes, and other machinery. Pushbutton switches may be used to monitor process parameters, provide feedback from machine to operator, or actuate machine functions. Pushbutton switches also provide safety features including travel interlock, door interlock, and emergency stop functions.

Working Principle

When a pushbutton switch is pressed the electric power is sent to the circuit it controls. The switch is composed of various electrical components that allow it to actuate the circuit when the button is pressed. Pushbutton switches have internal springs that hold the contacts open when the button is not pressed. When the button is pressed the springs are disengaged and the contacts are closed. The contacts can be either normally open (NO) or normally closed (NC).

When an NO switch is open the circuit it controls has no power. When the button is pressed, the contacts are closed, which allows the power to flow to the circuit it controls. Similarly, when an NC switch is pressed, the power is disconnected from the circuit. Pushbutton switches can be wired in series, parallel, or a combination of both to control a circuit.

Several types of pushbutton switches exist, including momentary and latching switches. Momentary switches stay in the pressed state until released. They provide a single-action operation, usually utilized to start or stop a process. Latching switches remain in the pressed state until it is pressed again. These are used for applications where the same command should be repeated multiple times.

Conclusion

The AOLD3QH211DNUW is an electromagnetic pushbutton switch used in variety of applications ranging from consumer products to industrial automation. Pushbutton switches are available in different sizes, shapes, and actuating options, and are either normally open or normally closed. Momentary or latching switches are available tp provide single action or repetitive action operations. Pushbutton switches provide reliable and durable switching of electrical contacts.
