Electromagnetic relay

An electromagnetic relay comprising:

• a base unit;
• an electromagnetic unit disposed on said base unit and operable for generating an electromagnetic force when being energized;
• a magnetic unit mounted to said electromagnetic unit and having
• a magnetic member that is connected fixedly to said electromagnetic unit and that has a fulcrum portion,
• a magnetic driven subunit that includes a pushing block and a magnetic component having:
• a magnetic driven portion that is supported on said fulcrum portion and that is magnetically attractable by said electromagnetic unit;
• and
• a levered portion that extends substantially transversely from one side of said magnetic driven portion and that is connected to said pushing block,
• an arcuate groove that is formed in one of said fulcrum portion and said magnetic driven portion, and
• an arcuate protrusion that is formed at another one of said fulcrum portion and said magnetic driven portion, that is pivotably connected to said arcuate groove such that said magnetic component is pivotable about said fulcrum portion relative to said magnetic member;
• a first conductive terminal disposed on said base unit and including a first contact;
• a second conductive terminal disposed on said base unit and including a second contact that is opposite to and spaced apart from said first contact;
• and
• a movable conductive terminal including
• a movable conductive connector that is disposed on said base unit, that is disposed between said first contact and said second contact, and that is pushed by said pushing block of said magnetic driven subunit when said electromagnetic unit is energized, and
• a movable contact that is disposed on said movable conductive connector,
• wherein, when said electromagnetic unit is energized, said magnetic component is magnetically attracted and driven by the electromagnetic force of said electromagnetic unit to move, such that said levered portion of said magnetic component drives said pushing block to push said movable conductive connector and that said movable contact contacts one of said first contact and said second contact, and when said electromagnetic unit is powered off, said magnetic component is not magnetically attracted by said electromagnetic unit, such that said movable contact contacts another one of said first contact and said second contact.
