摘要

Improvements in the thermostatic devices current switches applicable to industrial or domestic cold rooms, which are essentially characterized by the fact that the closure or opening of the circuit is made by a system of two levers of substantially parallel axes, these levers are tilting and independent, related to each other by an arched leaf spring in which the leading edge of the control lever is in a plane lower than the axis of rotation of the receiving lever, opening or closing the electrical circuit to the contact of the lever receiver with one or another tip of two screws in which one of them is in contact with the circuit.
