What is the difference between 2-wire and 3-wire control?

The two types of ladder control circuits commonly used are the 2-wire control circuit and the 3-wire control circuit. The 2-wire control circuit uses maintained contact devices to control the magnetic motor starter. The 3-wire control circuit uses momentary contact devices to control the magnetic motor starter.
