Abstract (en)
[origin: EP0693763A1] The switch includes an envelope (E) enclosing a pole, and first and second main fixed contacts (1a,2a) situated along the length of the internal wall of the envelope. These contact cooperate with two main mobile contacts (5a,6a) carried by a conductor bridge (4) which is able to rotate. The switch also includes a vacuum (D) containing a fixed contact (9) and a mobile contact (10). One of these contacts (10) is connected to one (1a) of the fixed contacts of the main switch, whilst the other is temporarily connected to the bridge (4) by the switching device (7,16). The sequential operation of the contacts ensures the use of the vacuum contact breaker at the required time. <IMAGE>
