Abstract
The present invention relates to a single-pole or multi-pole switch to be used preferably in low-voltage systems. The switch () comprises an outer casing () containing for each pole at least one fixed contact () and one mobile contact () that can be coupled to/uncoupled from one another. The mobile contacts () are housed in appropriate seats () provided on a mobile element (). The switch () moreover comprises an energy-accumulation control mechanism (), operatively connected to the mobile element () to enable its movement. The switch () according to the invention is advantageously provided with means of axial support operatively connected to the mobile element () in order to support the gravitational thrusts that are generated along the axis of rotation of the mobile element itself when said axis is inclined with respect to a substantially horizontal plane.
