Patent ID: 7750259

Claim:
A multi-pole switch ( 1 ) for low-voltage systems comprising: an outer casing ( 2 ), containing for each pole at least one fixed contact ( 10 ) and at least one mobile contact ( 20 ), which can be coupled to/uncoupled from one another; a mobile element ( 50 ), defined by a shaped body comprising at least one seat ( 25 ) for each pole of said switch ( 1 ), said seat ( 25 ) being designed to house at least one mobile contact ( 20 ) of a corresponding pole; and an energy-accumulation control mechanism ( 60 ) operatively connected to said mobile element ( 50 ) to enable its movement, wherein said switch comprises means of axial support, operatively connected to said mobile element ( 50 ), said outer casing comprises a bottom ( 3 ), which is coupled to a lid ( 4 ) through geometrically mated coupling surfaces, said mobile element ( 50 ) comprises a plurality of mutually adjacent seats ( 25 ), set between which are connecting parts ( 55 a , 55 b ) in a position corresponding to which said supporting means are operatively connected to said mobile element ( 50 ), said mobile element ( 50 ) comprises a first circular connecting part ( 55 a ) and a second circular connecting part ( 55 b ), each located between two adjacent seats, said first part ( 55 a ) and said second part ( 55 b ) comprising a first radial recess ( 51 ) and a second radial recess ( 52 ), respectively, and each of said seats ( 25 ) is defined by a front wall ( 26 ), a rear wall ( 27 ) substantially opposite to said front wall ( 26 ), a first side wall ( 28 ) and a second side wall ( 29 ) substantially opposite to one another, said surfaces ( 26 , 27 , 28 , 29 ) defining at least one first opening ( 23 ) and one second opening, from which there come out, respectively, said mobile contacts ( 20 ) and junction means ( 47 ), designed to connect electrically said mobile contacts ( 20 ) to respective electrodes ( 22 ) of said switch ( 1 ).
