An actuator comprising: An electric switch apparatus equipped with the actuator.

Electromagnetic actuator and switch apparatus equipped with such an electromagnetic actuator

An electronic control device for a switch unit, which includes an electromagnetic actuator having a control coil powered by an excitation current for closing a power electrical circuit. The electronic control device includes a storage unit for storing at least one coil control profile which contains a plurality of values representative of the excitation current as a function of respective points of time. A drive unit is connected to the storage unit, and receives at its input an external close command and controls at its output the excitation current at respective points of time from the receipt of the external close command to follow the plurality of excitation current values of said control profile during the closing of the power circuit. The drive unit operates in open loop mode, without using information relating to the switch unit that includes at least a measurement of an excitation current at the control coil.
