Abstract: An electromagnetic relay includes an electromagnetic unit, a magnetic unit, first and second contacts, and a movable conductive terminal. The magnetic unit has a magnetic member having a fulcrum portion, a magnetic driven subunit, an arcuate groove, and an arcuate protrusion. The magnetic driven subunit includes a pushing block for pushing the movable conductive terminal, and a magnetic component magnetically attractable by the electromagnetic unit. The arcuate groove and the arcuate protrusion are respectively and interchangeably formed in the fulcrum portion and the magnetic component, and are pivotably connected to each other such that the magnetic component is pivotable about the fulcrum portion relative to the magnetic member. The movable conductive terminal is driven by the electromagnetic unit to contact one of the first contact and the second contact.
