VGA012FB is a type of voltage-controlled switch application in electric systems that provides a means of switching from one voltage source to another. This type of switch has been around for many years and is often used in utility applications due to its reliability and cost effectiveness. It is highly reliable due to its use of a single mechanism to control the switching process, and its low cost comes from its simple design that has minimal material and mechanical parts.

VGA012FB is a mechanical switch that is operated by an electric current. It has two primary components: the contacts and the actuator. The contacts are made up of two metal plates that provide a current path between the switch and the voltage source. The actuator is the part of the switch that is powered by an electric current and is responsible for opening or closing the contacts. The actuator is connected to the contacts via a mechanical linkage, and this linkage is designed to open or close the contacts depending on the amount of electric current that is supplied to the actuator.

The VGA012FB application field includes but is not limited to utility companies, industrial plants, electrical distributors, and instrumentation systems. It is utilized in several applications, including switching between two power sources, switching between two different voltage sources, controlling loads in multiple-load systems, and providing a fail-safe means of remote monitoring. In addition, it is suitable for controlling switching between two high and low voltages, enabling the use of low voltage components such as surge protection devices or remote control systems.

The working principle of VGA012FB is based on a simple, but effective switching process. When a current is applied to the actuator, the linkage moves, which in turn opens and closes the contacts. Depending on the magnitude of the current, the contacts will open or close, which controls the flow of current from the voltage source.

When the contacts are open, the electric current does not flow through the switch, and hence, no current is supplied to the voltage source. However, when the contacts close, the flow of current is enabled and a fixed current is supplied to the voltage sources. This in turn drives the voltage as required.

The VGA012FB is a highly reliable and cost-effective switch, and it is suitable for a wide range of applications. It allows remote switching of voltage sources and can provide a fail-safe means of remote monitoring. In addition, it can operate at both high and low voltage levels, as well as in multiple load systems.
