摘要
The sensor has a movable transmission element (4), functionally coupled to the belt (2) and an electrical switch (7) with a contact system (8) which is closed when an abnormal length change or a rupture of the belt occurs. The contact system has a switching contact spring (9) having a contact surface (13) at the opposite end to that which is coupled to the transmission element and provided with 2 offset arms (11,12), clamped to the carrier (26) of the switch for cascade operation of the contact system.
