Rotary Changeover Switch Wiring Diagram: A Comprehensive Guide

A rotary changeover switch is a type of switch that can connect different circuits to a common circuit. It has a rotary knob that can be turned to select the desired connection. Rotary changeover switches are commonly used in electrical systems to change between the primary and backup sources of power, among other applications.

Wiring Diagram of Rotary Changeover Switch

A rotary changeover switch is wired differently depending on its application. Nevertheless, the basic principle remains the same. A rotary switch has a common terminal, which is connected to the circuit that is common to all the connections. It also has multiple terminals that are connected to the different circuits that can be selected. The terminals are numbered or lettered for easy identification.

The wiring diagram of a rotary changeover switch usually consists of a schematic representation of the switch and its connections. The diagram shows the terminals of the switch and how they are connected to the circuits. The wiring diagram also shows the voltage and current ratings of the switch and the circuits, and any other relevant information.

The Rotary Switch

The rotary switch is the main component of the wiring diagram. It is depicted as a circle with a knob or lever attached to it. The knob or lever is turned to select the desired connection. The switch has a common terminal and multiple terminals that are connected to the different circuits.

Terminal Identification

The terminals of the switch are identified by numbers or letters. The identification is usually printed on the switch or provided in the manufacturer’s documentation. The common terminal is usually identified as “C” and the other terminals are identified as “1”, “2”, “3”, and so on.

Connecting the Circuits

The circuits that are connected to the switch terminals depend on the application. In a power system, for example, the primary and backup sources of power are connected to the switch terminals. The switch is then turned to connect the desired source of power to the common circuit. In other applications, the switch may be used to select different modes of operation or control different devices.

Wiring the Switch

The switch is wired according to the wiring diagram. The common terminal is connected to the common circuit and the other terminals are connected to the respective circuits. The connections can be made using wires, connectors, or other suitable means. It is important to observe proper wiring practices to ensure safety and reliability of the system.
