Rocker switches are electric devices that are used to control a circuit. The device consists of an actuator, which is operated by pressing it down to initiate the circuit closing or by lifting off to open the circuit. The DT22J12S2AHQA is a rocker switch with specialized properties suitable for a wide range of applications. This article reviews the common applications and workings of this rocker switch.

Main Applications

The DT22J12S2AHQA is designed with an illuminated red rocker switch and most commonly used in major electrical devices such as air conditioners, ovens, microwaves, washing machines, dishwashers, and other household appliances. It is also suitable for automobile applications such as power seats and electrical power supplies. Other applications can include industrial material handling and controlling equipment, medical and laboratory equipment, as well as industrial automation and numerous other control systems.

Working Principle

When the DT22J12S2AHQA is activated, it closes the electrical circuit and the current will start flowing. Once the circuit is closed, the switch is in the “on” position and illuminating a bright red LED light. This LED is used to indicate the connection status, facilitating easier maintenance and diagnostics, as well as reducing wiring requirements. When the switch is in OFF position, the circuit is open and no current flows.

The switching action of the DT22J12S2AHQA is accomplished by a sealed plunger that fits tightly within an actuator. When the plunger is pushed, it moves an armature that is connected to electrical contacts. This initiates the electrical circuit as the contacts become connected, allowing current to pass through. When the switch is retracted, the armature is pushed back by springs, which open the circuit, interrupting the flow of current.

The DT22J12S2AHQA has several safety features designed to protect against short circuits, overloads and other electrical anomalies. These include a reset feature, surge protection, and a power-on/off switch. The reset feature turns off the device if the circuit is overloaded, while the surge protection prevents too much current from flowing through at once. The power-on/off switch turns the device off manually, which can also be used to reset the switch.

Conclusion

The DT22J12S2AHQA is a rocker switch that is widely used in a multitude of applications. Its primary feature is its red illuminated switch, which facilitates diagnostics and reduces wiring requirements. The switch is activated by a sealed plunger that fits within an actuator, allowing currents to pass when the switch is in the ON position. To protect against overloads, the switch is equipped with several safety features, including a reset feature and surge protection.
