Pushbutton Switches are an important and widespread device. Almost every electronic device has some type of switch which allows user in to operate the device, or tell the device the requirement of various switching environment. AOFD202NUB is one of the most commonly used switches, and is mainly used in commercial, industrial and military applications. This article will discuss the application field and working principle of AOFD202NUB.

AOFD202NUB pushbutton switch is a two-pole double throw switch, which is mainly used for wiring up two circuit paths in a single device. It is available in a range of sizes, from 6mm to 25mm, and is normally PCB-mounted. The contact ratings of this switch is 10A/125VAC and 4A/250VAC, making it suitable for a wide range of applications, such as audio equipment, automotive and medical devices.

In terms of working principle, AOFD202NUB switch is an electromechanical device. It consists of a switch mechanism, a fulcrum, which when moved by the user will rotate the contacts. The contacts consist of two plates that move in or out of contact when the switch is operated. When the switch is in the ‘off’ position, the contacts remain open and no current is able to pass through them. However, when the switch is pushed down, the plates move together and the current can pass through them. The switch will return to the open position when the user releases the switch.

AOFD202NUB switch is also available in a plunger-actuated version, which includes a movable plunger, a spring, and a contact. The plunger is used to move the spring, which in turn pushes or pulls the contacts and closes the circuit. This type of switch requires a relatively low operating force, and has a higher contact life than other types of switch.

As stated earlier, AOFD202NUB switch is suitable for a wide range of applications, and is used in various industries such as audio, automotive, medical and industrial applications. For example, in the audio industry it is used for switching between speakers, for selection between different audio sources and for muting the audio signal. It is also used in automotive applications for switching between warning systems, for operating indicators, for maintainance functions and for controlling the power on/off of the vehicle. It is widely used in medical device, such as infusion pumps, because of its compact size and high contact ratings.

In summary, AOFD202NUB pushbutton switch is a widely used switch in commercial, industrial and military applications. Its working principle is based on an electromechanical mechanism, and can be actuated by a plunger or by a single contact. It is available in a range of sizes, and has a high contact life. Its versatility make it suitable for a wide range of applications, such as audio equipment, automotive and medical devices.
