The present disclosure relates to an operating member including: a support; an actuating part, which defines an actuating surface is mounted on the support by a mount to be movable relative to the support, by manual actuation against a resetting force, while carrying out an actuating movement from a rest position into a depressed position; a detector having at least one force sensor, wherein the detector is adapted to detect at least one position of the actuating part; wherein the mount includes a guidance mechanism having at least one pair of coupled levers, wherein the levers are each pivotably mounted on the support by a first pivot joint and on the actuating part—by a second pivot joint to cause a pivoting movement of the at least one pair of coupled levers by the actuating movement, wherein the guidance mechanism further includes at least one coupling rod.

An improved contactor device for high current switching applications, in particular industrial or railways applications, is provided, wherein a high DC current must be switched on and off, the contactor device includes a switch base portion including an electric switching mechanism of a high voltage portion and an arc extinguishing portion covering the switching mechanism. The contactor device includes a couple of moving contacts driven towards and away from each other with respect to a mutual contact and abutting position, those moving contacts being mounted at the respective contact ends of a toggle mechanism activated by a low voltage driving portion incorporated in the switch base portion and active on the toggle mechanism.
