Rocker Switches

Rocker Switches, often referred to as "rocker arm switches," are a type of switch that is actuated with a rocking motion. These switches are available in a variety of sizes, shapes, and mount configurations, but the principle and function remain the same. The U21J52ZQE22 is a type of Rocker Switches that is designed for applications up to 250VAC.

U21J52ZQE22 Application Field

The U21J52ZQE22 Rocker Switches are ideal for a wide range of applications. These switches are able to provide long life and reliable switching performance, while remaining economical and easy to install. The U21J52ZQE22 is specifically designed for automation and industrial applications where power is managed with different levels, such as switch system, security systems, machine tool, electric door locks, and automated temperature control systems.

U21J52ZQE22 Working Principle

The U21J52ZQE22 Rocker Switches feature a balanced actuating torque mechanism and heavy-duty contacts for long life operation. When the actuator is rocked, the contacts move and make or break an electrical connection. Depending on the switch configuration, it is possible to connect different levels of voltage in an electrical circuit.When the switch is in the OFF position, the U21J52ZQE22 locks the contacts in the open position, making the switch circuit safe for maintenance. The strong and reliable construction of the switch provides reliable performance, even after repeated switching cycles. The mechanical life of the U21J52ZQE22 Rocker Switches is rated at 10,000 cycles minimum.

Installation and Maintenance

Installation of the U21J52ZQE22 Rocker Switches is simple and straightforward. Since it is a panel-mount type switch, it can be easily affixed onto the panel with the help of two mounting screws. When installing the switch, it is important to ensure that the screws are tightened securely to prevent any kind of electrical failure. The switch should also be installed in an area where it is free from dust and other forms of contamination.Once the switch is installed, it should be tested for any irregularities before being put into service. The switch should be kept clean to prevent dust from collecting on the contacts. In addition, the contacts should be inspected regularly for any signs of wear or damage. If any damage is observed, the switch should be replaced to ensure continued safe operation.

Conclusion

The U21J52ZQE22 Rocker Switches are a reliable and economical option for applications up to 250VAC. With its reliable contacts and adjustable actuation torque, this switch is designed to provide years of trouble-free operation. It is easy to install and requires minimal maintenance, making it an ideal choice for industrial applications.
