Snap Action, Limit Switches

Also known as limit switches, snap action switches are electromechanical devices used to detect the presence or absence of an object. They are also used to determine the position of an object, and to monitor and regulate mechanical movements. Commonly used in industrial automation and industrial control systems, snap action switches provide a significant benefit in terms of accuracy, repeatability, and reliability.

The GLDA04B snap action switch is an optimal switch for applications in many industrial settings. It is a multi-turn type of snap action switch, with an adjustable cam and contact combination for excellent repeatability and reliability. Moreover, the switch is robust and dependable with excellent mechanical strength.

Working Principle of the GLDA04B Snap Action Switch

The GLDA04B snap action switch consists of three sections: a rotary base, a cam assembly, and a contact system. The rotary base holds a cylindrical chamber containing the cam assembly, which is generally made from plastic with several pins or studs extending from its sides. The contact system is comprised of two parts: a stationary contact and a sliding contact.

The cam assembly pivots within the chamber as the cam is turned by the controlling shaft with connection points on either side of the cylindrical chamber. As the cam turns, it pushes the contact system away from each other, thus opening the switch. When the cam is turned the other way, it pulls the contact system back together and closes the switch.

The cam is kept in either the open or closed position by a snap action mechanism. The cam passes over a lever connected to a spring. As the cam moves, it presses the lever down, and when it reaches the end of its travel, the lever snaps back up, pushing the cam into place and either opening or closing the switch.

Application Fields of the GLDA04B Snap Action Switch

The GLDA04B snap action switch is suitable for applications in many industries, such as automation, conveyors, food and beverage, robotics, machine tools and medical equipment. A sample of its possible applications include, but are not limited to:

• Controlling the orientation and positioning of robotic arms and legs
• Detecting the presence, position, and/or absence of parts in automated assembly lines
• Monitoring the end of travel of motors and pumps
• Detecting the opening and closing of process valves
• Monitoring the performance of production machinery in food and beverage bottling lines
• Monitoring the temperature of heat treating equipment

Additionally, the GLDA04B differs from other snap action switches in that it offers an adjustable cam and contact combination that increases its accuracy as well as its repeatability and reliability. This is especially important in applications in which precision and repeatability are key concerns.

Conclusion

The GLDA04B is a reliable and robust multi-turn type of snap action switch for industrial applications. It offers an adjustable cam and contact combination for excellent accuracy, repeatability and reliability, making it an optimal switch for use in various robotic applications, automated assembly lines, and heat treating equipment, among others.
