Vacuum switch

Abstract

Vacuum switch (100) for switching an electrical circuit comprising an evacuated tube (300), a fixed contact (500), a moving contact (410) mounted on a movable support bolt (400), and a kinematic mechanism (600) for moving the support bolt (400) between a first position in which the moving contact (410) mechanically interacts with the fixed contact (500) to close the electrical circuit, and a second position in which the moving contact (410) is mechanically separated from the fixed contact (500) to open the electrical circuit, wherein the kinematic mechanism (600) comprises a lever (610) movable about a pivot point D, which moves the movable support bolt (400) between the first position and the second position, wherein the movable lever (610) is attached to the support bolt (400) directly or indirectly by means of a retaining bolt (631), and wherein at the ends of the retaining bolt (631) Support sleeves (650) are attached, characterized by,that the respective diameter of the support sleeves (650) is such that the support sleeves (650) cover both all parts of the fastening of the support bolt (400) or of the support bolt (400) itself, as well as all parts of the lever (610) in all lever positions between the first position and the second position in a direction perpendicular to the direction of the retaining bolt (631).
