Snap Action, Limit Switches: 3AC68 Application Field and Working Principle

Snap action, limit switches are used to control the operation of industrial motors, contactors, solenoids and other electric parts. The 3AC68 switch is a commonly used snap action, limit switch. It is designed for AC operations. The 3AC68 switch offers a wide range of application possibilities in industrial operations, due to its compact design, high switching accuracy and reliable performance.

Application Field

The 3AC68 switch is a single-pole, double-throw switch with a rated voltage of twenty-four volts. It is mainly used in the automation industry, integrated with various terminals and sensors to respond to the operator’s commands. Typical applications include motor start and stop control, remote on/off control, adjusting and monitoring the speed of motion, and 3D printing. It can also be used in other fields such as robotics, lighting, and signaling.

Working Principle

The 3AC68 switch is constructed of an electromechanical assembly consisting of a rotor and a stator, connected by a link. As the assembly rotates, contacts open and close. When a certain point is met, the switch contacts are opened or closed, allowing for the transmission of electronic signals. By adjusting the position of the actuator, the 3AC68 switch can be configured for either latching or momentary operations.

The 3AC68 switch is also designed to self-reset after each actuation to prevent accidental overlatching. Aside from that, the switch has additional features such as reverse lockout capability, terminal wrenches, and snap-in rivets. The switch also has automatic self-alignment features that guarantee accuracy in operation.

Comparison with Other Switches

Compared to other snap action, limit switches, the 3AC68 switch offers a good combination of performance and price. It is sturdier than other similar switches, and it is also less expensive. It offers a wide variety of features, such as adjustable power rating, adjustable actuator force, and snap-in rivets. Additionally, it is easy to install and configure, and it also offers some degree of "intelligence": it can detect and react to new potential situations.

Conclusion

The 3AC68 switch is a widely used, versatile snap action, limit switch. It is mainly used in the automation industry, where it can be integrated with other terminals and sensors for various operations. Its compact design, high switching accuracy, reliable performance, and additional features make it a great choice for industrial operations at a relatively low price.
