Improvements to latchkeys and corresponding magnetic locks for control of accesses

摘要

The improvements consist in the lock 10 having a single series of magnetic sensors 27 and in the groove of the actual lock being replaced by an inclined plane 26 made on the front plate 25 of the lock and suitable for being applied externally to the functional part of the latchkey; the rear face of said inclined plane 26 incorporates said single series of sensors 27 which identify the polarity or the absence of each magnet of the latchkey. <IMAGE>
