The connection of the thyristor flip-flop circuits' goal is to achieve a longer response time ranging between tens of milliseconds to seconds by a short enabled pulse. The connection is arranged in such a way that a limiting resistance (3) is connected to the positive terminal (2) of the power supply in series with the rectifier diode (4), to whose cathode the break contact unit of the relay bond of contacts (5) is connected, which is on the change-over contact connected to the time condensator (6) and the anode of the switching thyristor (10). The anode of the serial diode (7) and one coil tag of the D.C. relay (8) are connected to the other side of the time condensator, while the make-contact of the relay bond of contacts (5), cathode of the serial diode (7) and the second coil tag of the D.C. relay (8) are connected to the negative terminal (1) of the power supply. The connection of this circuit with the variable resistance (9) that is connected parallel to the coil of the D.C. relay (8) is also possible.<IMAGE>
