Abstract

A switching device comprising: a plurality of switching mechanisms configured to connect and disconnect a power supply from a load, the plurality of switching mechanisms arranged along a first axis and each comprising a fixed contact and a moveable contact; and an actuating mechanism for simultaneously actuating the plurality of switching mechanisms. The actuating mechanism comprises: a bridge configured to move the movable contacts of the plurality of switching mechanisms; a shaft arranged along a rotational axis parallel to the first axis, wherein the shaft is configured to rotate around the rotational axis; and one or more force transmittal mechanisms configured to convert torque from the rotation of the shaft to a linear force acting on the bridge in a second direction. The second direction is perpendicular to the first axis. Movement of the bridge in the second direction brings the moveable contacts into electrical contact with the fixed contacts.
