<p>An electronic lock comprises at least one touch swich (P1) enabling to input in series a pulse train corresponding to a lock code. Independently from a predetermined time raster, the pulse train which has been inputted is compared to stored code values. If they match, an actuation signal is triggered which controls an opening mechanism. If the results of the comparison is negative, the input operation may be repeated. A blocking or an alarm is activated if a predetermined number of repetitions is reached. Return signals facilitate the inputting of the code. The touch swich may be integrated, optionally with optical sensitive devices, without projecting, in curved or cracked surfaces.</p> |
