The disclosure relates to an electromagnetic relay that comprises a yoke and an armature. The armature may be swivellably arranged on the yoke, have an open position and a contact position in relation to the yoke, and configured to be attracted by a magnetic field out of the open position into the contact position. The armature may include a first branch circuit having a first capacitor and a first exciter coil connected in series with the first capacitor, a second branch circuit having a second capacitor and a second exciter coil connected in series with the second capacitor, and a switch element arranged between the first branch circuit and the second branch circuit and having a first switch state and a second switch state. The first exciter coil and the second exciter coil may provide the magnetic field for attracting and retaining the armature.
