Toggle Switches are an important type of device used in most electrical systems and they provide an efficient way to manually switch power between two different sources. One of the more popular toggle switches is the 2TL28-1, which is widely used throughout the industry. In this article, we will take a closer look at its application field and working principle.

Applications of the 2TL28-1

The 2TL28-1 toggle switch is designed to control single-phase or three-phase electrical devices and circuits, such as contactors, relays, lighting ballasts, pumps, motors and other AC or DC loads. This switch can be found in a variety of settings, from office automation equipment, electrical panels and distribution boards, to industrial and agricultural machines and equipment.

The 2TL28-1\'s high operating temperature rating of 105C, its high IP protection levels, high mechanical life and low contact resistance make it an ideal choice for a variety of applications. Its reliability and robust construction make it especially well-suited for industrial and coastal locations.

Working Principle of the 2TL28-1

At the heart of the 2TL28-1 toggle switch is a set of highly conductive contacts, which are able to carry current between the two poles inside the switch. When the switch is in the “on” position, the contacts close and current is able to pass through the switch. When the toggle is switched off, the contacts break the circuit, thus preventing current flow.

The contacts are mounted on a pair of toggle plates, which are attached to the operating handle via a connecting rod. When the handle is moved, the connecting rod transfers the motion to the toggle plates, which then actuate the contacts. This allows users to easily switch the switch without having to use complex electrical circuitry.

The 2TL28-1 also features an overload protection system, which prevents damage to the contacts caused by excessive currents. This feature protects the contacts from electrical arcing and premature wear, thus ensuring reliable operation and a long service life.

Conclusion

The 2TL28-1 is a popular toggle switch that can be found in a variety of applications. It features high IP protection, an overload protection system, and an operating temperature rating of 105C, making it a reliable choice for a variety of settings. Finally, its simple toggle mechanism ensures ease of use and makes it a great choice for all your switching needs.
