A system for controlling a motorised component of radiological equipment using a device with a control lever having a first end constrained to a base manoeuvred by gripping a handle with a hand. First and second electric sensors are associated with a grip of the control lever. The first electric sensor is located at a first point of the grip and adapted to detect the presence of a finger. The second electric sensor is located at a second point of the handle of the control lever and adapted to detect the presence of a finger at the second point. Another electric sensor is for detecting the positioning of the control lever with respect to the base. An electronic unit is connected to the electric sensors for causing movement as a function of the positioning of the control lever only if the first and/or second electric sensors detect a presence.
