Les éléments de contact (8) sont disposés par rapport au circuit de manière telle que pour ladite congruence (91), seuls des éléments de contact (8) électriquement compatibles les uns avec les autres sont représentés superposés les uns sur les autres. Cette configuration permet de réduire à un minimum les dommages subis par des personnes et/ou des biens, sans qu'une protection contre l'inversion de polarité mécanique et/ou électrique soit nécessaire.
