Rotary switches provide electric power control over a wide range of devices, ranging from simple household appliances to industrial machinery. The E2G0402S series of rotary switches are manufactured by TE Connectivity and are designed for applications that require a precision, heavy duty rotary switch.

Specific Features

The E2G0402S switch has a unique three-position design that allows for switching current or voltage in either direction. It also has a one-piece housing with a zinc die-cast back plate, which helps to protect against corrosion, and it is sealed to IP68 specifications. Additionally, the switch has an integrated strain relief and is UL94-V0 rated for safety.

Application Fields

The E2G0402S series rotary switch can be used for a variety of applications, ranging from home appliances and consumer electronics to aerospace, industrial and medical equipment. In consumer electronics, the switch can be used to control audio/video devices, adjust fans and dimmers, and control power in other appliances. The switch can also be used in aerospace and industrial applications, such as test and measurement, life safety and industrial control systems, where it is capable of controlling devices or machines up to three times the rated current or voltage.

Working Principle

The E2G0402S switch works by using a spring-loaded mechanism to rotate a cam-shaped drive, which turns two or more rotating disks or spools around an axis. When the axis is turned with the turn handle, the air gap between the contact surfaces of the disks or spools increases or decreases, which in turn switches current or voltage during the movement. The switch is constructed in such a way that the cam and the disks are always in contact with each other, thus ensuring reliable operation over a wide range of temperatures and humidities.

Conclusion

The E2G0402S series of rotary switches from TE Connectivity offers a reliable and durable solution for applications that require higher current and voltage control, such as those found in consumer electronics, aerospace, industrial and medical equipment. The switch features a three-position design and a one-piece housing with a zinc die-cast back plate, which helps ensure it is well protected against corrosion and dust. The E2G0402S also has an integrated strain relief and is UL94-V0 rated for safety, making it an ideal choice for a variety of applications.
