Rotary switches are a type of electrical switch used to establish an electrical connection between two or more poles. The A11205RSCB rotary switch is a rotary switch with a contact block built into it. It has 4 positions: off, forward, reverse, and an off bump used to disengage the forward and reverse positions. The A11205RSCB has two terminals at each end, and the contacts are connected in series. It also has an overload protection feature that prevents it from switching beyond its rated current capability.

The A11205RSCB is designed for use in a variety of applications, such as motor control and industrial control applications. It is commonly used to control the direction of a motor, by providing a forward or reverse direction. In addition, it can be used to control the speed of a motor, by providing different combinations of forward and reverse directions. It is also used to control the starting and stopping of a motor, by providing a momentary contacts.

The A11205RSCB is constructed from a die cast aluminum housing, with a molded plastic contact block. The contact block allows for the connection of two terminals at each end, with a third terminal (off bump) located in the center. The contact block is sealed to the housing to provide protection against moisture and dust.

The operating principle of the A11205RSCB is simple: when the switch is turned in either the forward or reverse direction, the contacts are closed, allowing a current to flow. When the switch is turned to either the off bump or the off position, the contacts are opened, breaking the connection and preventing a current from flowing. The overload protection feature works by limiting the current through the switch, and preventing it from switching beyond its rated current capability.

In summary, the A11205RSCB is a rotary switch with a contact block and overload protection built into it. It is used in a variety of applications, such as motor control and industrial control applications, and the operating principle is based on closing and opening the contacts to either allow or prevent a current from flowing.
