An electromagnetic relay is provided. The electromagnetic relay includes a first port and a second port, a first coil and a second coil, a movable armature coupled between the first port and the second port constructed to connect and disconnect the first port and the second port, a switch circuit, and a coil control circuit. The switch circuit is constructed to connect the first coil to an external power source to induce the first coil to create a first magnetic field having a first direction and disconnect the first coil from the external power source to cause the first magnetic field to collapse. The coil control circuit is constructed to induce the second coil to create a second magnetic field having a second direction responsive to the switch circuit being in the second state, the second direction being opposite the first direction. |
