A low voltage apparatus includes a mechanical interlock,which comprises at least two contactors, wherein every contactor includes a base (11, 21), a support (12, 22), a top cover (4) and a contact holding sliding part (13, 23) in the base. Two contactors which are arranged in parallel both have one mechanical interlock, which includes an interlocking element (3). The shaft of the interlocking element (3) may rotate in the groove of the base (11, 21). By the swinging of the interlocking element (3), a tentacle of the interlocking element (3) extends into the locking aperture of the contact holding sliding part, thereby preventing the connecting action of the contact holding sliding part. |
