Pushbutton Switches have been widely used in an array of different applications and can be found in many different fields. SER, BK, AU, and OA are among the different pushbutton switches technologies. Different switches are used for different applications, such as lighting, door locks, and more. In this article, we will discuss the SER, BK, AU, and OA application fields, as well as the working principles of each switch.

SER Application Field

SER stands for Single-Pole, Edge-Rocker. This switch is characterized by a single toggle or rocker mechanism which actuates each time the switch is pressed. SER switches are used in a variety of applications, including fire alarm systems, doorbells, and more. They are often used for simple "on-off" applications when the switch does not need to be used for a longer duration.

BK Application Field

BK stands for Two-Pole, Edge-Rocker. This switch is similar to the SER switch, but with two different poles. This allows two circuits to be closed at the same time when the switch is actuated. BK switches are used in applications where two separate circuits must be activated simultaneously, such as in the operation of a garage door opener. This switch can also be used in a variety of other applications, such as burglar alarm systems and sprinkler systems.

AU Application Field

AU stands for Momentary-Action, Edge-Rocker. This is a type of switch that is used in applications where the switch needs to be held down for a certain period of time before it will operate. This switch is used in applications where the user needs to maintain control over the switch, such as in the operation of a doorbell. AU switches are also commonly used in the operation of fire alarm systems, as well as in programs that require the user to enter a code into the system.

OA Application Field

OA stands for One-Axis, Edge-Rocker. This type of switch is used in applications where the user needs to be able to control the speed of operation. A single toggle or rocker mechanism allow the user to control the speed of the operation by the amount of force applied to the switch. OA switches are used in applications such as garage door openers and motorized gates.

Working Principles

The working principles of SER, BK, AU, and OA switches are all based on the use of a single toggle or rocker mechanism. This mechanism works by allowing the user to actuate the switch, which then completes an electrical circuit. This circuit closes and opens, depending on the application and the switch specifications. For example, SER switches are used for simple "on-off" applications, while BK switches are used for applications that require two circuits to be closed at the same time. Additionally, AU switches are used for applications that require the switch to be held down for a certain amount of time, while OA switches are used for applications that require the user to be able to control the speed of the operation.

In conclusion, pushbutton switches are used in a variety of different applications, and SER, BK, AU, and OA switches are among the most commonly used types. Each of these switches is used for a specific application, and their working principle is based on the use of a single toggle or rocker mechanism. Understanding the differences between SER, BK, AU, and OA switches can help ensure that the correct switch is chosen for the desired application.
