What is a 3 pole double throw switch?

A 3 pole double throw Switch (3PDT) is an electromechanical device that can be used to control three separate circuits, each with two possible conduction paths. The switch has three common poles, each of which can be connected to one of two throws, allowing the user to switch between two different output paths for each pole. This type of switch is often used in situations where it is necessary to change between two different states or circuits, such as in electrical power systems, complex machinery, or signal routing in audio applications. The double throw nature allows for more complex switching arrangements than a simple on-off switch, providing increased versatility in controlling electrical circuits.
