Rotary switch (1) which comprises a rotating control shaft (2) provided with a plurality of cam disks (4) respectively associated to a plurality of current breaking devices (5), each current breaking device (5) being linearly displaceable within a base (6) between a connected position and a disconnected position of a pair of electrical connecting strips (7). Each current breaking device (5) comprises a mobile bridge assembly (9) provided with a plastic support (10) mounted on elastic means (11) and a metal bridge (12) coupled on said plastic support (10), said metal bridge (12) being able to maintain direct contact with the respective strips (7) by means of the release force of the elastic means (11) in the connected position, and to move away from said strips (7) when the mobile bridge assembly (9) is pushed by the cam disk (4), compressing said elastic means (11) in the disconnected position. |
