A low voltage electrical appliance having a mechanical interlock means 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 means, which includes an interlocking element (3). The shaft of the interlocking element (3) may rotate in the slot of the base (11, 21). By the swinging of the interlocking element (3), a tang of the interlocking element (3) extends into the locking aperture of the contact holding sliding part, thereby preventing the energization action of the contact holding sliding part. |
