YZ-2RDS5551-A22 Switches

Snap action and limit switches such as YZ-2RDS5551-A22 are essential components in various industries and applications. The two types of switch components take advantage of the elasticity of metal materials to reset the contact with a distinct "Snap!" sound and action when an electrical current is applied. Such devices usually manifest in the form of a metal lever or rod; when connected to an appropriate level of current within an external circuitry, the switch rapidly snaps into a new position.

Applications

YZ-2RDS5551-A22Snap action, limit switches are vital components in a multitude of electrical systems, including tamper switches, ignition and ignition systems, door open alarms, doorbells, fire alarms, temperature control systems, and temperature gauge systems. In most cases, the switch must remain unchanged until the current is flowing and then quickly reset when the current is interrupted. This distinctive "snap" action is produced by the lever and rod link that produces a draw back force when the current is ceased.

This type of switch is popular with industrial applications due to the reliable and efficient operation. Such switches are suitable for use with high-voltage circuits, low-voltage circuits, high-current circuits, and mechanical power systems. Furthermore, they may be used with a variety of actuators, including toggle levers, paddle levers, roller levers, and ultra-sonic sensors.

Limitations

One limitation to this type of switch is that it is not suitable for use in applications where a full 360 degree rotation of the actuator is needed. Additionally, this type of switch can suffer from a number of common design flaws and malfunctions. Poorly designed or manufactured switches may fail to reset after the current has been interrupted. This could result in a continuous drain of energy from the system, potentially damaging the equipment.

Working Principle

Snap action and limit switches consist of many components, including a conductive metal rod and lever, a contact surface, and a spring. When an electrical current is applied, the spring activates, causing the metal rod and lever to press against the contact surface. The contact surface then converts the electrical current into a mechanical movement. This produces the distinctive "snap" sound and action as the lever is rapidly restored to its original position.

The force of the lever pressing against the contact surface is carefully designed to ensure that the correct amount of pressure is applied when the switch is activated. Both the contact surface and the energy of the spring are carefully calculated so that the switch does not become too weak or become stuck in place.

Conclusion

YZ-2RDS5551-A22 is a popular snap action, limit switch component suitable for a range of industrial applications. Such switches are capable of providing a reliable and efficient operation using a variety of actuators. However, the switch is limited by a few design flaws, including insufficient rotation and the possibility of becoming stuck in place or failing to reset. Nevertheless, these switches work in principle by converting electrical current into mechanical movement by pressing a conductive metal rod and lever against a contact surface.
