An electric switch selector, also known as a rotary switch or selector switch, is a type of electrical switch that allows the user to select and control different positions or functions within an electrical circuit. It is commonly used in various applications where multiple options or settings need to be chosen.

The electric switch selector consists of a rotating knob or lever that can be turned or positioned to different settings or positions. These settings are typically represented by markings or labels around the switch, indicating the different functions or options available.

Inside the switch, there are multiple electrical contacts or terminals arranged in a circular or semicircular pattern. As the switch is rotated or positioned, its internal mechanism connects or disconnects different contacts, thereby establishing different electrical connections within the circuit.

Each contact or terminal of the switch is associated with a specific function or position in the circuit. For example, in an audio system, a selector switch may be used to choose between different input sources such as CD player, radio, or auxiliary input. Each position of the switch corresponds to a different input source, and the selected position determines which source is connected to the output.

Electric switch selectors can have different configurations depending on the number of positions and contacts they offer. They can range from simple two-position switches to more complex multi-position switches with numerous options.

These switches are commonly found in electronic devices, control panels, machinery, and appliances where the user needs to select and switch between different modes, functions, or settings. They provide a convenient and reliable means of controlling electrical circuits with multiple options.It is realistically designed to suit all projects and uses and on all programs
