YA-2RV-A2

Snap Action, Limit Switches

When considering a device that provides a specific electronic signaling function, it is essential to select a device that will meet the requirements for its application field. The YA-2RV-A2 snap action, limit switch manufactured by Omron Automation is a prime example of a device that can be used in a variety of applications with reliable performance.

The YA-2RV-A2 is a single pole double throw switch that features a snap-action switch designed to produce an instantaneous response when actuated. The contact system of the switch is rated to carry up to 5 amp of current at 277 VAC or 125 VDC and provides a minimum of 500,000 electrical operations when actuated. The switch is also designed with momentary contact and is sealed to prevent dust and other environmental hazards from entering the contact system.

The switch is suitable for a variety of applications including air conditioning units, process controllers, industrial automation, and other general on/off switch applications. It is important to note that the switch should not be used with currents or voltages exceeding the rated contact system specifications. The device is also not suitable for actuators that exceed the rated electrical contact force.

When installing the YA-2RV-A2 switch, it is important to make sure that the unit is securely fastened to the actuating mechanism or surface. The device should also be firmly secured in order to ensure that unintended motion does not cause damage to the contact points. This will help to ensure the optimal performance and longevity of the switch.

Working Principle

The working principle of the YA-2RV-A2 snap action, limit switch is relatively simple. The device features a movable contact point attached to a lever arm that is in contact with a fixed stationary contact. When the switch receives an actuator signal, the lever arm is pushed or pulled, causing the contact point to move and establish a connection between the two contact points. This connection produces an electrical signal, providing the signal required for the desired application. This type of switch is sometimes referred to as a "make before break" switch due to the fact that the connection is made before the previous connection is broken.

The YA-2RV-A2 is a reliable and versatile switch that can be used in a variety of applications. The device is designed to ensure reliable and consistent performance in its designated application with minimal maintenance or service. With its sealed construction, the switch is well protected from potential environmental hazards and its contact system is specially designed to provide reliable low contact resistance and long life.
