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.
Dispositif basse tension à verrouillage mécanique comprenant au moins deux contacteurs constitués chacun d'une base (11, 12), d'un support (12, 22), d'un couvercle supérieur (4) avec, dans la base, une partie coulissante de maintien de contact (13, 23). Deux contacteurs disposés en parallèle comportent chacun un dispositif de verrouillage mécanique ave élément de verrouillage (3). L'axe de l'élément de verrouillage (3) peut tourner dans une rainure de la base (11, 21). Lorsque l'élément de verrouillage (3) pivote, un doigt de cet élément pénètre dans l'ouverture de verrouillage de la pièce coulissante de maintien de contact, ce qui empêche cette dernière d'établir la connexion.
