A branch disconnect switch (BDZW2) is a switch component used to separate a branch from the main circuit and selectively control access to various parts of the main circuit. This type of device is commonly used on electrical networks and motors. It consists of two or more contact elements that can be opened and closed with an appropriate handle or lever.

The BDZW2 switch’s application field varies depending on the size of the required current and the working environment. Typically, such switches are used for low and medium current applications in domestic, commercial, industrial and agricultural settings. In the railway industry, BDZW2 switches are used to electrically connect different parts of the railway network, usually via a single pole switch system. One example is the use of a BDZW2 on a railway signal box, which is a metal housing containing control levers, each one connected to a single or multiple block switch. The lever is then used to control access to the railway network.

The working principle of a BDZW2 switch is relatively straightforward. When the switch is closed, current flows from the main circuit to the branch circuit, allowing electrical apparatus to be operated or power to be distributed. When the switch is open, the circuit is broken and no current is able to flow. In the switch’s open position, the handle remains locked with a system of springs and rods. This prevents any accidental opening of the switch and provides a failsafe mechanism for maintaining the circuit in the open state.

From a safety perspective, BDZW2 switches are generally designed to be completely disconnectable from the mains. This feature ensures that the switch can safely be tested or serviced without the need to shut down the adjacent circuits or networks. The switch’s operating mechanism also typically incorporates a test button, which allows the electrical system to be tested prior to switching, ensuring that all power connections are in the correct state.

The BDZW2 switch provides safety and convenience when connecting and disconnecting a main circuit from a branch circuit, and is available in a number of different voltage and current ratings, as well as operating temperature ranges. Its application field and working principle can be adjusted to meet the specific requirements of each situation. The switch is commonly used as an isolation device between different parts of a single circuit, or between multiple circuits of varying voltages or currents.
