Abstract: A linkage device adapted to control two electric switches including a main control shaft member, an actuation system including a first actuation member for actuating a control shaft of a first electric switch, and a second actuation member for actuating a control shaft of a second electric switch. A mechanism of the linkage device is provided with a torque limiting connection for each electric switch, wherein the torque limiting connection is adapted to disengage during an opening event if a torque exerted to an actuation member exceeds a predetermined limit value. The linkage device includes a stopping member system adapted to co-operate with a linkage arm system for preventing rotation of the main control shaft member to an OFF-position when the torque limiting connection of at least one linkage arm of the linkage arm system is in a disengaged position.

Abstract: An adapter for an electric switch assembly, the adapter having an adapter body adapted to be immovably connected to an electric switch including a first set of terminals, wherein each of the terminals includes a terminal member adapted for releasing a connection between the terminal and the corresponding electric wire. The adapter includes a protective cover movably connected to the adapter body such that the protective cover has a protection position and a first installation position, wherein in the protection position the protective cover is adapted to prevent use of the terminal members of the electric switch, and in the first installation position the protective cover is adapted to enable use of terminal members of the first set of terminals, wherein said use of a terminal member includes releasing a connection between the terminal and the corresponding electric wire.

Abstract: A switching device including a frame, a first fixed contact member having a first contact area, and a first movable contact member having a first contact arm provided with a contact area. The first movable contact member is adapted to pivot relative to the frame around a first pivoting axis between a first position and a second position. The switching device includes a spreader member that is adapted to provide a first intermediate position for the first movable contact member in which a projection of the contact area of the first contact arm overlaps at least partially with a projection of the first contact area on a switch plane perpendicular to the first pivoting axis while the contact area of the first contact arm is spaced apart from the first contact area.
