Rotary Switches

RBP12 403B03 N S S rotary switch is a network device used to provide manual control and switching of circuits. It consists of a knob, a shaft, a contact, and a frame. Rotary switches can be used to select between two or more circuits, or to establish a path between two circuits. It is mainly used in industrial and power systems to control the flow of electricity.

Application Field

Rotary switches are mainly used in the fields of industrial, instrumentation, communication and power systems. In industrial applications, they are used to control circuits, motors, and other equipment to keep machines running efficiently and safely. In instrumentation, rotary switches are used for calibration, input/output, power/indicator/test equipment, and panel/console switches. In communications, rotary switches are used for cable and phone line control, and relay control. In power systems, they are used for various aspects of electrical control, such as circuit protection, circuit overlaying and circuit switching.

Working Principle

A rotary switch works by using the inertia of the rotational movement of the switch knob, which is connected to a shaft, to actuate the switch contacts of a contact block assembly. When the knob is rotated, the contacts are opened, and when the knob is released, the contacts close. Depending on the position of the knob and the arrangement of the contacts, the switch can be in one of two or more positions, allowing different circuits to be connected. The number of positions of the switch can be adjusted according to the requirements of the system.

The most common types of rotary switches are multi-pole switches, which are used in applications where multiple circuits need to be switched on and off. These switches are designed with multiple contact paths, each of which can be used to connect multiple circuits. The number of contact paths is determined by the number of poles in the switch. Some types of rotary switches have levers or buttons that can be used to change the position of the switch at a faster rate.
