Abstract
An improved case for electro-automatic switches, characterized by the fact that between the terminals of the box plate there is a system of levers combined together, subjected to the reaction of their own springs, whose enclave and balance is conditioned by a tilting trigger, whose The locking position is ensured by the tension of an elastic spring connected at one end to the normal connecting wire between the outlet edge of the box and the trigger, and at the other end the spiral spring itself is connected to a thermowilable conductor arranged in parallel with the normal connection.
