Abstract:
A relay device may include an armature that moves between a first position that electrically couples the armature to a first contact and a second position that electrically couples the armature to a second contact. The relay device may also include a relay coil that receives a voltage to magnetize the relay coil, thereby causing the armature to move from the first position to the second position. The relay device may also include a drive circuit that couple the voltage to the relay coil, such that the voltage is higher than a rated voltage associated with the relay coil.
