WZ-2R-A2

Snap action and limit switches are one of the most important components in automation technology. The WZ-2R-A2 switch is a good example of this technology. It can be used for many applications, and its basic principles of operation are relatively simple.

The WZ-2R-A2 snap action limit switch is used to detect the presence of an object in a certain zone. This switch is activated by the presence of an object in the designated zone. As the object enters the zone, the switch will open and close its contact points accordingly, thus providing a signal to activate a device.

The WZ-2R-A2 is equipped with a dual-contact system. This system includes two contact points which are normally closed, and one contact point which is normally open. When the object enters the designated zone, the two contact points will open and close, depending on the size and shape of the object. In other words, the larger and thicker the object, the more contact points will open.

The WZ-2R-A2 switch is also equipped with a snap action mechanism. This mechanism consists of two main elements. The first element is a bar which is pushed against an external trigger. When the external trigger is activated, the bar is displaced and the contact points are opened and closed accordingly.

The second element of the snap action mechanism is a spring. The spring is usually located inside the switch, and its function is to return the bar back to its initial position when the external trigger is released. This ensures that the contact points remain closed until the next external trigger.

The WZ-2R-A2 switch can be used in a variety of applications, including automated control systems, security systems, and industrial machinery. In control systems, the switch is usually used as an on/off switch for certain devices, such as lights, motors, and solenoids. In security systems, it can be used to detect the presence of an intruder, and to activate an alarm system. In industrial machinery, the switch is commonly used to limit the speed of a machine, or to detect the presence of an object.

The WZ-2R-A2 snap action limit switch is an excellent tool for automation technology, as it is relatively durable and easy to install. Its simple operation ensures that it can be used in a variety of applications, and its dual contact system ensures that it can detect objects of different sizes or shapes. With its simple installation and operation, the WZ-2R-A2 is an ideal switch for any automated environment.
