Abstract
Automatic intermittent switch characterized by its operation being based on the expansion and contraction of a conductor with a small section which is used to close and open an electrical circuit that in the first case allows the supply or ignition of one or more lamps of signals giving rise in the second to the cessation of said power supply and extinguishing of those lamps, said switch being constituted by a base or platform of insulating material of suitable shape and dimensions and eventually provided with the means to receive a hood or protective cover for all the apparatus on the base of which are mounted an electromagnet whose core is attached to a current input terminal, the coil of the aforementioned electromagnet being connected on the one hand to the terminal to which the signal lamp (s) will be applied and, on the other hand, to a thermal resistance arranged in series with the extensible wire that retains an armature attached to the core and The contacts of the thermal circuit keep one of whose contacts is part of the aforementioned armature while the other is connected in a bypass of the coil, leaving the set established in such a way that in the initial phase of operation the current that passes through the core armature resistance dilatable wire coil and filament of the lamp is absorbed by the mentioned resistance due to its high value compared to that of the filament of said lamp produces the expansion of the tensioning wire which leaves its armature free by closing the latter by its own action the contacts of the thermal circuit whose components - resistance and wire - are short-circuited p roasting the current only through the coil armature and signal lamp that turns on instantly because the absorption resistance has disappeared and then the first phase in which the supply is interrupted, with the consequent cooling of the resistance and wire.
