Toggle Switches are a common type of electrical switch used in everyday life. The 29ET20-3B-E is a single pole, double throw toggle switch (SPDT) that is versatile, reliable, and good value for a price. It is ideal for switching between two applications or power sources and is commonly used in a variety of industrial, automotive, and commercial applications. In this article, we will discuss the application fields and working principle of the 29ET20-3B-E toggle switch.

Applications

The 29ET20-3B-E toggle switch is widely used in a variety of industrial and commercial applications. It is especially useful for applications where alternating between two power sources or applications is required. These sources can be either AC voltage or DC voltage and could range from as low as 1 Volt to as high as 250 volts. Common applications include audio equipment, lighting control systems, automobile electronic systems, battery management systems and electronic circuit boards.

The 29ET20-3B-E is also used for safety and security purposes. It can be used to control access to restricted areas in a facility or building. On the walls of factories, it can be used to close off hazardous areas or to control the flow of electricity to potentially dangerous equipment. It can also be used as a control switch in alarm systems or other security systems as it is capable of controlling both AC and DC voltage.

The toggle switch is also found in a variety of hobby projects. From simple lighting automation and robot control systems, to more complex electronic hardware, the 29ET20-3B-E is great for crafting next level projects. Hobbyists and enthusiasts around the world use the toggle switch in their projects, as it is a versatile and reliable part.

Working Principle

The 29ET20-3B-E toggle switch has three poles and two throws. The first pole is the common or ground pole and the two throws are connected to the two power sources. Upon switching the toggle, one or the other of the power sources is connected to the common or ground pole while the other is disconnected. It is like having two power switches in a single package.

The toggle switch is a mechanical switch and works on the principle of an electrical contact being made when the toggle is switched. The toggle itself is made of gold-plated copper and is built to endure extended periods of use and to resist corrosion and oxidation. The gold-plating inhibits oxidation on the copper terminals and ensures smooth electrical contact.

The mechanical contact is made by two encapsulated stationary contacts (numbered 1 & 2) and a movable contact inside the toggle switch. When the toggle switch is in the “off” position, neither of the two stationary contacts is connected to the movable contact. When the toggle switch is in the “on” position, one of the two stationary contacts is connected to the movable contact and the other is disconnected. By using this principle, one of the two power sources is connected to the common pole when the toggle switch is switched “on”. The switch is actuated by a built-in spring which returns the toggle switch to the “off” position when released.

Conclusion

The 29ET20-3B-E toggle switch is a reliable, versatile, and affordable switch ideal for switching between two power sources or applications. It is used in a variety of industrial, automotive, and commercial applications as well as hobby projects. It is a single pole, double throw switch that works on the principle of electrical contact being made when the toggle is switched. The switch is actuated by a built-in spring which returns the toggle switch to the “off” position when released. With its gold-plated copper internals, the switch is built to last and can endure long-term use and abuse. Its versatility and functionality makes it a great choice for almost any application.
