Snap action limit switches are basic electromechanical switches. They use a physical plunger which when pressed actuate a pair of contacts and this helps switch a circuit on and off. When a certain distance is travelled by the plunger, it will create a sudden, definite motion or snap action. This snap action can be recreated with each use.

The WA-2RV178-A2 is a limit switch that utilizes snap action. It is a miniature single pole/single throw switch. It uses a tin plated strip contact to close when the lever is pressed by a plunger. When the plunger is released, it bounces back to the normal open position. The WA-2RV178-A2 is designed for a wide variety of applications where space is limited.

The WA-2RV178-A2 is manufactured using high-quality materials and advanced techniques. It has a cam-action mechanism that allows quick and positive contact action and is built to withstand multiple mechanical life cycles. This switch is UL recognized, CSA certified, and meets EN 61058-1 requirements.

The WA-2RV178-A2 is used in various fields, such as automation, robotics, consumer electronics, medical instrumentation, automotive and industrial controls. The switch can be used to sense the position of the plunger or actuator in the control system. It is designed to detect when a part has shifted from one position to another, or to detect when an object has passed a certain point.

The WA-2RV178-A2 has a working principle that utilizes the snap action of a plunger. The plunger is placed against a fixed contact and when pressed, the contact closes and changes the circuit state. The contact will open when the plunger is released, bouncing back to the open position. This snap action of the plunger keeps the contacts open while not in use and then allowing the switch to be used again and again.

The WA-2RV178-A2 is an excellent example of a snap action limit switch. It is easy to install, reliable and is suitable for a variety of applications. Built with high-quality materials and advanced techniques, this switch is able to provide hundreds of thousands of cycles. It is a versatile switch and can be found in commercial, automotive and industrial applications.
