| 摘要 |
The present invention relates to a single-pole or multi-pole switch to be used preferably in low-voltage systems. The switch ( 1 ) comprises an outer casing ( 2 ) containing for each pole at least one fixed contact ( 10 ) and one mobile contact ( 20 ) that can be coupled to/uncoupled from one another. The mobile contacts ( 20 ) are housed in appropriate seats ( 25 ) provided on a mobile element ( 50 ). The switch ( 1 ) moreover comprises an energy-accumulation control mechanism ( 60 ), operatively connected to the mobile element ( 50 ) to enable its movement. The switch ( 1 ) according to the invention is advantageously provided with means of axial support operatively connected to the mobile element ( 50 ) 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.
