Toggle Switches: The 7108K12ZGE

Toggle switches are electrical switches that turn on and off through the action of a toggle. They are often used to connect and disconnect circuits instantly and manually. The 7108K12ZGE is a particularly versatile and reliable toggle switch, offering users multiple configurations and high current ratings. Read on to learn more about its application fields, construction, and working principle.

Overview of the 7108K12ZGE Switch

The 7108K12ZGE switch is manufactured by E-Switch, Inc. It is a single-pole, double-throw (SPDT), center OFF toggle switch with a actuator. It is designed to handle high inrush current ranging from 4A to 8A with electrical life of up to 10,000 cycles. The switch has an operating voltage of up to 125 V AC or V DC and a contact resistance of less than 50 mΩ.

It is available with four different actuator styles: illuminated round, illuminated square, round bezel, and a quiet switch. The illuminated versions offer multiple LED colors to choose from, while the quiet switch has a quieter operation compared to standard toggle switches. This switch also features a snap-in mounting style and is available with four different termination options: vertical PC pins, right-angle PC pins, quick connect terminal, and solder lugs.

Application Field

Due to its versatile design, the 7108K12ZGE is suitable for a wide range of applications. It is commonly used in consumer electronics, industrial equipment, test equipment, medical devices, and many other applications that require manual on/off operation. It is particularly suitable for applications where high power is required for switching or controlling. The illuminated versions can also be used as a panel light switch for added visibility.

Construction

The 7108K12ZGE switch is constructed using a heavy-duty die-cast zinc alloy body for durability and corrosion resistance. It is sealed against dirt and moisture, making it suitable for both indoor and outdoor use. The actuator is constructed of a high grade Nylon 6/6, which is strong and resistant to wear and tear. The switch contains a pair of contacts that are connected to the terminals via a contact bridge.

The switch is designed to be mounted onto printed circuit boards and is secured by screws. It has an operating temperature range of -10 °C to +70 °C, making it suitable for most environments. The switch also complies with IP67 protection levels, ensuring that it is dust tight and protected against temporary water immersion.

Working Principle

The 7108K12ZGE switch works by using a toggle between two contact forms, switching the electrical circuit on and off. When the toggle is moved, it will either make contact with the upper contact or lower contact, sending the electrical current in one direction or the other depending on which contact is made. This allows the user to manually control the flow of electricity.

The switch is also designed to prevent short circuits. Since the contact bridge is not connected to the terminals, electricity travels only through the contact form in which the contacts are placed. This ensures that the switch is safe to handle and use.

Conclusion

The 7108K12ZGE Toggle Switch is a reliable, versatile device that can be used for numerous applications. With its various actuator styles and termination options, it is suitable for a variety of conditions and environments. Moreover, its rugged construction and tight seals prevent dirt and moisture from entering, providing users with a reliable, durable switch.
