Abstract (en)
[origin: EP1420432A2] The contact system has a switch piece (10) for each pole of the low voltage (LV) switch, supported in the switch housing via a floating bearing and acted on by a contact spring. The switch housing has a first stop cooperating with a first switch piece section at the end of the opening movement and a second stop cooperating with a second section of the switch piece, offset angularly from the first stop. A bearing pin (15) of the switch piece is supported within an elongate opening (27) for providing the floating bearing, the longitudinal direction of the opening extending parallel to the acting direction of the contact spring and allowing a rotation of the switch piece after abutting the second stop about a rotation point provided by the latter.
