Electromagnet with contact protrusions

An electromagnet with contact protrusions is applied to contactors and various control or protection electrical devices and comprises an I-shaped or C-shaped core, a core limiting support, a coil fixed on the support, an elastic member, and at least one C-shaped yoke component, wherein one end of the elastic member is fixed to the support, the other end of the elastic member is abutted to the core and the C-shaped yoke components opposite to the core are fixed on the support. The electromagnet is characterized in that opposing fitting surfaces of a yoke of each yoke component and the core are provided at least one integrated protrusion. The protrusions are integrally formed by stampings, and the size precision is easy to control. The protrusions are simple to manufacture, convenient to mount and suitable for clearance control of the electromagnet, and stability of the electromagnet is improved.
