Abstract
"ELECTRICAL SYSTEM FOR KEY CONTROL OF ELECTROMECHANICAL DEVICES" which is characterized by comprising a set of relays formed by as many units as the code has the key, connected in such a way that, except for the corresponding to the first number, the operation of each of them is conditioned to the operation of the relays relative to the previous figures; further comprising a control device constituted by a set of push-button switches, conveniently referenced, which is located in an accessible place outside the closing device, each of said buttons being connected to the corresponding contacts of a group of selecting devices in which the mobile contact element of each of them is part of the excitation circuit of one of the previous relays, there being therefore as many selectors as numbers of the key, allowing said selectors to choose each figure of the key between any of the references indicated on the pushbutton switches that constitute the command; further comprising a blocking device constituted by series contact of the selectors and an auxiliary relay whose power circuit is only interrupted when the switches corresponding to the figures of the key have been pressed and in the established order; so that only in that case the electromagnet circuit of the closing device is closed.
