Title: GEARING BETWEEN A MOVABLE SWITCH CONTACT AND A DRIVE OF A POWER SWITCH
Abstract:
The invention relates to a gearing (7) between a movable switch contact (3) and a drive (5) of a power switch (1). The gearing (7) comprises a drive lever (9), an output lever (11) and a coupling unit (13). The drive lever (9) and the output lever (11) are movable between two switching positions, wherein the movement of the drive lever (9) is a rotation about a drive axis of rotation (21) which is perpendicular to a drive lever longitudinal axis (19) of the drive lever (9), and the movement of the output lever (11) is a rotation about an output axis of rotation (25) which is perpendicular to an output lever longitudinal axis (23) of the output lever (11). The coupling unit (13) converts the rotations of the drive lever (9) into rotations of the output lever (11) with a transmission ratio with a magnitude of less than one.
