Rocker switches are one of the most commonly used switches found in a range of devices and appliances. WR19AT is one of them. In this article, we are going to take a look at its applications and working principle to get a better understanding of this type of switch.

Applications of WR19AT

WR19AT is mainly used for controlling the circuit on/off in low-voltage applications. It is widely applied in battery operated circuits such as lamp controllers, small fans, toys, and many other circuit control applications. Additionally, this type of switch is designed to provide reliable and easy handling in most applications, making it a go-to choice for a variety of applications.

WR19AT Working Principle

A WR19AT switch is a single-pole double-throw (SPDT) switch, which means it has one input and two output contacts. When you press the switch down, the output is connected. When you release the switch, the output is disconnected. As a result, you can control the output voltage or current as you need. The output current is low, so the switch has a better power saving performance.

The switch is composed of three parts, a base, a button, and a sliding rocker. When the rocker is pressed, it slides and connects the two output contacts. The switch also has two resistors and two LEDs. When the switch is on, the two resistors provide a connection from the input terminal to the output terminal, and the two LEDs will light up. The whole working process is powered by a battery.

Conclusion

All in all, WR19AT is a simple switch that can be used for a variety of applications. It is an SPDT switch with low output current and two LEDs that can indicate the device’s working status. It has a simple and reliable design, which is what makes it the perfect choice for low-voltage circuit control.
