Pushbutton switches are well-known devices for enabling or disabling electrical power or a particular circuit. The A165-AAM-2 is one type of pushbutton switch which offers a broad range of features and applications. Understanding the features and working principle of the A165-AAM-2 can help users make the most of its capabilities.

Applications of the A165-AAM-2 Pushbutton Switch

The A165-AAM-2 pushbutton switch is designed for use in a variety of locations, including safety-related control systems. It is suitable for use in industries such as electromechanical, transportation, automotive, marine, aerospace, and more.

Within these industries, the switch can be used for a variety of operational control functions, such as starting and stopping machinery and equipment, controlling motors and conveyors, or even turning lights or other systems on or off.

The switch is designed with a single button and is rated to IP66 protection, meaning it is suitable for both indoor and outdoor applications. The switch is also rated to work with AC/DC circuits of up to 250V and 6A; it additionally has a locking mechanism, allowing the user to select between momentary and latching modes, as well as allowing for the isolation of the contacts when not in use.

Working Principle of the A165-AAM-2 Pushbutton Switch

When the button is pressed down, the switch creates an electrical connection, allowing electricity to flow and activating the system. The electrical contacts are made of a combination of copper and silver, which make for a solid, reliable connection.

The switching mechanism is a little more complicated. Inside, the switch has a toggle switch, a hopf switch, and a momentary contact switch. When the button is pressed, the toggle switch opens, the hopf switch closes, and the momentary contact switch closes. This creates an electrical connection, enabling the system to be activated.

If the switch is in the latching mode, then when the button is pressed down, the hopf switch will stay in the closed position and the toggle switch will stay in the open position. This creates a continuous electrical connection, allowing the system to continue running until the switch is manually reset.

The switch also uses a combination of a microswitch and a plunger mechanism. The plunger is used to control the movement of the microswitch, which allows the switch to be actuated when the button is pressed down. This motion then activates the hopf switch and the momentary contact switch, completing the electrical connection and activating the system.

Conclusion

The A165-AAM-2 pushbutton switch is a highly versatile device which can be used in many locations and for a variety of operational control functions. Understanding its features and working principle can help users make the most of its capabilities.
