Rotary switches have been around since the late 19th century, and plays an important role in various industrial control systems due to its structure and design features. The 412-7T3E is a type of rotary switch often used in electrical panels and other applications requiring frequent cycling. In this article, we will take a look at the application field of the 412-7T3E rotary switch and its working principle.

Accurate Positioning & High Frequency of Operation

The primary application field of 412-7T3E rotary switch is in the industrial electric power control equipment and the electrical control systems. Its working principle is dependant on the basic mechanism of rotary switches. The 412-7T3E switch is constructed around a plastic-based rotary wafer that is secured with two rings of wire springs. It is then wrapped with a capacitor-like plastic guard.

When operated, its rotor head rotates to connect two or three fixed contacts that are connected together. This results in the selection of several different positions for the switch position and also providing accurate positioning for each position. Connecting these contact points will enable the operation of the associated device or equipment. The 412-7T3E rotary switch can also be operated without fail at very high frequencies of operation, even at a frequency of up to millions of times per second.

Main Features

The 412-7T3E rotary switch is designed to be of a small size and curved configuration, making it ideal for switches mounted in confined spaces in electric panels. It features a conductive rating of up to 8 Ampere and a contact resistance of 20 Milli Ohm, with an insulation resistance of 200 Meg Ohm. The 412-7T3E switch also offers a long life cycle, with an expected life span of up to 100,000 operating cycles with minimal wear and tear. The contact material used in the switch is silver alloy, which provides a good contact performance for a variety of operations.

The 412-7T3E also offers a protection of IP67, which means it is dust- and water-tight. This offers extra level of protection when used in electrical control panels. It is also maintainable under a voltage of 250 Volt and can also be used in both dry and damp environments.

Applications

The 412-7T3E switch is widely applicable in a variety of electric and power control equipment. It can be used to control various motorized door openers, motorized staircases, voice recognition systems and surveillance systems. It is also suitable for the switching control systems of industrial machines, and is found in many electric panels.

Conclusion

The 412-7T3E rotary switch is a durable and reliable switch type that is widely used in a variety of industrial control systems due to its precise operation, high frequency operation and weather-tight seal. It is also available in a variety of configurations, allowing for flexibility and customization to suit the operational needs of various applications.
