Abstract

The improvements consist in each magnetic assembly of the latch key 1 being formed by a single magnet 5, at the same time as, in the lock 2, there are two sensors 3i,3d for said magnet, in such a manner that when the latter is placed over the lock, the sensor 3d will detect whether said magnet 5 is to the right if it is to the left, the sensor 3i will detect this, sending the relevant signal to the central electronic unit if the magnet 5 is in an intermediate position, both sensors 3d,3i will send one or no signal to said central unit.
