U211J3Z3QE2 application field and working principle

Rocker switches are a type of electrical switch used to control a variety of circuits. And U211J3Z3QE2 is one type of the common rocker switches. As for U211J3Z3QE2, its application field is mainly on the machine tool, and other industrial equipments. And it can be adapted different environment and circuits.

The Working Principle of U211J3Z3QE2

The working principle of U211J3Z3QE2 is most the same with other rocker switches. Its structure mainly includes four terminals, a rocker, a spring, and a button. Generally, the terminals of U211J3Z3QE2 contain two positions: an \'ON\' position, and an \'OFF\' position. And the two positions are marked by arrows which can indicate if the switch is open or closed.When the switch is in the \'OFF\' position, the spring will help the rocker to move back to the \'ON\' position once the user presses the button. The four terminals will also be connected. Then, the switch can establish the switch circuit and user can get the output power. On the contrary, when the user releases the button and the switch goes to the \'OFF\' position, the spring cannot push it back, and the switch will stay at the \'OFF\' position. In this case, the switch will break the circuit, and user can not get the output power.As the simple and reliable working principle, U211J3Z3QE2 has been widely used in the machine tool, and other industrial equipments. And it is an ideal cost-effective choice for users.

Safety Reminders

Although U211J3Z3QE2 has been designed to ensure safety, users should pay attention to the rocker switch current and voltage ratings before using. It is dangerous to go beyond the current and voltage ratings of the switch. Moreover, users should also check other safety instructions carefully, in order to ensure a safe use.In addition, if users find that the rocker switch is damaged or fault, or can not get the proper output power, users should stop their work immediately, and look for professional help for further repairing.
