Electromagnetic contactor

摘要

The disclosed electromagnetic contactor has a base including a lateral opening and an internal space, and two rails disposed at the bottom of the internal space. A U-shaped stationary iron core including two guides on both sides is assembled into a coil holder so that one leg of the "U" is surrounded by an operating coil held by the coil holder. Then the coil holder is inserted into the internal space in the base through the lateral opening with the guides engaging the rails until it is removably positioned in the internal space.
