An AH765479-A Snap Action, Limit Switches is an electrical device that provides a momentary, open or closed connection. It is typically used to provide control signals or to trigger commands within an electrical system or to provide an indication of system status or conditions. The AH765479-A Snap Action, Limit Switches has a contact arrangement consisting of single or double-pole single-throw (SPST or DPST) contacts. It may also have other types of switching arrangements, such as double-pole double-throw (DPDT) or 3-way contact combinations.

The AH765479-A is designed with a crescent-shaped armature that is attached to an actuator. When the switch is activated, the armature quickly snaps into a predetermined overlapping position with a contact pad to provide an instantaneous open or close connection. The spring-loaded arms enable the contacts to move quickly thus giving the switch its “snap action” characteristic. This switch type is well suited for use in high vibration applications due to its ability to quickly move the contacts.

The AH765479-A Snap Action, Limit Switches is used in many applications such as in industrial and consumer electronics, electrical power distribution/control, consumer appliances, medical equipment, and toys. Some of the most common applications include controlling lighting and other electrical devices, providing indication or notification of system or equipment conditions, and initiating control functions.

The working principle of the AH765479-A snap action, limit switch is straightforward. When the actuator is actuated, the armature quickly snaps into an overlapping position with a contact pad thus providing an instantaneous open or close connection. Generally, an internal spring provides the force necessary to move the armature to the closed position. Depending on the application, other mechanisms such as movement of a lever style actuator may also be used.

The AH765479-A snap action, limit switch offers a variety of features to suit many applications. These features include modular and panel mounting options, multiple contact arrangements, and contact ratings of up to 10A at 125/250V AC, 1A at 28V DC and 0.4A at 125V DC. In addition, AH765479-A features various contact shapes and actuator types including round, hex, rectangular, and plunger, as well as incorporate various circuit configurations through the use of contact blockers.

In conclusion, the AH765479-A snap action, limit switch is a reliable, cost-effective, and widely used electrics switch solution. Its design allows it to be used in a variety of applications and its features make it conducive to most applications. This switch type can be used to control lighting, providing system condition notifications, or initiating control functions. The snapshot action of the switch is beneficial when used in high vibration applications and its features and contact ratings make it suitable for many applications.
