Abstract: A utilization unit (500) of an electric switch comprises an actuator module (100) which includes actuators and power transmission apparatus to operate the electric switch (600), a power module (200) which includes power supply means for the actuators of the actuator module (100), a control module (300) which includes control means to control the power module (200), and data transmission means. The actuator module (100), the power module (200), and the control module (300) constitute a modular structure, whereby the power module (200) and the control module (300) are detachably connected to each other and the actuator module (100) so that the power module (200) and the control module (300) are both separately replaceable in the utilization unit (500).
