An electric latch for a door leaf of a motor vehicle comprising: - a bolt capable of pivoting about its axis between an angular position for locking up a strike and a position for releasing the strike, - a pawl capable of pivoting about its axis between an angular locking position in which the pawl is likely to cooperate in abutment with a notch (101, 102) of the bolt so as to retain said bolt in a position for locked up the strike and a retracted angular position in which the bolt is freely rotatable about its axis, - a central opening lever, said lever being bearing on the pawl and capable of displacing said pawl into its retracted angular position, - an actuator intended to occupy three abutment positions and capable of cooperating with the central opening lever, said actuator including: - a driver including a driving toothed wheel and a coaxial driven wheel, the driving toothed wheel being capable of rotatably driving the driven wheel by means of a first drive member and said driven wheel including a second drive member, - a motor provided for rotatably driving said driving toothed wheel of the driver by means of a worm screw, - a central transfer lever capable of being displaced in translation by the driven wheel of the driver by means of the second drive member and whose movement is capable of being transmitted to the central opening lever to displace the pawl to its retracted angular position, such as one of the wheels (2,5) of the driver includes a first oblong aperture in the shape of an arc of a circle and the other wheel (2,5) includes the first drive member extending through said first aperture, the driver being capable of performing a rotary stroke of a wheel (2,5) without rotatably driving the other wheel (2,5). - a bolt capable of pivoting about its axis between an angular position for locking up a strike and a position for releasing the strike, - a pawl capable of pivoting about its axis between an angular locking position in which the pawl is likely to cooperate in abutment with a notch (101, 102) of the bolt so as to retain said bolt in a position for locked up the strike and a retracted angular position in which the bolt is freely rotatable about its axis, - a central opening lever, said lever being bearing on the pawl and capable of displacing said pawl into its retracted angular position, - an actuator intended to occupy three abutment positions and capable of cooperating with the central opening lever, said actuator including: - a driver including a driving toothed wheel and a coaxial driven wheel, the driving toothed wheel being capable of rotatably driving the driven wheel by means of a first drive member and said driven wheel including a second drive member, - a motor provided for rotatably driving said driving toothed wheel of the driver by means of a worm screw, - a central transfer lever capable of being displaced in translation by the driven wheel of the driver by means of the second drive member and whose movement is capable of being transmitted to the central opening lever to displace the pawl to its retracted angular position, such as one of the wheels (2,5) of the driver includes a first oblong aperture in the shape of an arc of a circle and the other wheel (2,5) includes the first drive member extending through said first aperture, the driver being capable of performing a rotary stroke of a wheel (2,5) without rotatably driving the other wheel (2,5). - a driver including a driving toothed wheel and a coaxial driven wheel, the driving toothed wheel being capable of rotatably driving the driven wheel by means of a first drive member and said driven wheel including a second drive member, - a motor provided for rotatably driving said driving toothed wheel of the driver by means of a worm screw, - a central transfer lever capable of being displaced in translation by the driven wheel of the driver by means of the second drive member and whose movement is capable of being transmitted to the central opening lever to displace the pawl to its retracted angular position, such as one of the wheels (2,5) of the driver includes a first oblong aperture in the shape of an arc of a circle and the other wheel (2,5) includes the first drive member extending through said first aperture, the driver being capable of performing a rotary stroke of a wheel (2,5) without rotatably driving the other wheel (2,5).
