The electronic lock is intended for safes, strong boxes, gates, etc. It is highly secure and swift in action using a simple scheme. It consists of a supply source (1), an electromagnet (2), consecutively connected keys (3), a signal bloc (4), transistor (5), resistor (6), a code switch (7), a zero-setting button (8), encoding keys (9) and restricting resistors (10, 11)<IMAGE>
