Abstract
A magnetic coil, a magnetic contactor using the magnetic coil and a method for manufacturing the magnetic coil are disclosed wherein the magnetic coil does not need increased winding space and can be configured as having two coil terminals protruding in only one direction or as having three coil terminals. A three terminal-type magnetic contactor which uses the magnetic coil does not require an increased amount of space for the winding process, and the size of the three terminal version is reduced while still meeting insulation requirements. The magnetic coil maintains reliable electrical connection even when subjected to mechanical vibration.
