Pushbutton switches, such as A3SJ-90A124EG, are used in many applications to switch an electrical current off and on. They are available in several different styles such as toggle, rocker and pushbutton. The A3SJ-90A124EG in particular is a two-pole maintained pushbutton switch that is typically used to control motors in applications where the switch must remain in the on position until the user intentionally operates the switch and manually holds the button down. The switch can also be incorporated into safety systems or locked out of service until purposely reset.

The A3SJ-90A124EG is an illuminated switch, meaning it has a pre-wired LED light and power supply built-in. The electrical contacts are rated to accept up to 30V and 9A and can be used in many applications to safely control either AC or DC electrical loads. The switch also has a snap action contact with a long life mechanical life of over one million operations.

The A3SJ-90A124EG also has a variety of features such as a dust resistant construction and a waterproof grade NEMA 4X rating. The contact arrangement can be normally open or normally closed depending on the application, and the indicator can be illuminated either red or green depending on the user\'s needs. For operation, the user simply presses the illuminated area of the switch to activate it.

The working principle behind a pushbutton switch, such as the A3SJ-90A124EG, is relatively simple. When the user presses the switch, an electrical current is connecting two terminals, either closing a normally open circuit or opening a normally closed circuit. This switch mechanism works by using an electrical contact, along with springs and other mechanical components, to open and close the circuit when the switch is activated.

In summary, the A3SJ-90A124EG two-pole maintained pushbutton switch is a reliable and versatile switch used in many applications. The built-in LED light allows the switch to be seen better during nighttime operations. The switch is capable of controlling both AC and DC loads, features a long life mechanical life, and is available in both normally open and normally closed configurations. For operation, the user simply presses the illuminated area of the switch to activate it. All in all, the A3SJ-90A124EG is a reliable and versatile switch for many applications.
