An elevator safety circuit powered by an electrical power supply at a first point terminal, said elevator safety circuit comprising: a safety circuit bypass detector characterised in that said safety circuit bypass detector comprises a plurality of switches serially connected to one another, said serially connected switches have a first and second ends, the first end is connected serially to said power supply and the second end is serially connected to said elevator safety circuit bypass detector having two ends, one end of said elevator safety circuit bypass detector is connected serially to the second end of said serially connected switches and the second end of said elevator safety circuit bypass detector is connected to a second point terminal, said second terminal is connected to an electrical load for moving an elevator car; said elevator safety circuit bypass detector have a first switching device with a normally open first contact and a normally close second contact, a second switching device with a normally open third contact and a normally open fourth contact; wherein, in normal operation when said switches are operated in a close position, first switching device is energized causing closing of the normally open first contact and opening of the normally closed second contact; second switching device is prevented from being energized since normally open third contact and normally closed second contact are in open state; whereby, from second point terminal in respect to ground an electrical signal transferred to said electrical load for moving an elevator car; in the event that at least one of said serially connected switches is malfunction, first and second switching devices (RX; RZ) are in off state causing first and third contacts (RX1; RZ1) to be in open state, thereby, a signal is not transferred from second point terminal in respect to ground to said electrical load for moving an elevator car; fourth contact in this event is in open state thus, an electrical load controller not receiving a signal from a third terminal, wherein in the event that at least one of said serially connected switches is malfunction and it is necessary to operate said load, said elevator safety circuit is temporary bypassed by electrically connecting said first point terminal to second point terminal; thereby said serially connected switches are bypassed and a signal is transferred from said power supply for allowing said load to operate; second switching device is energized facilitated by the normally closed second contact of first switching device that is in close state; the energized second switching device causes normally open third and fourth contacts (RZ1; RZ2) to both operate in a close state; second switching device causes fourth contact to be in a close state and the signal generated from said power source is received also from the third terminal for further processing. a safety circuit bypass detector characterised in that said safety circuit bypass detector comprises a plurality of switches serially connected to one another, said serially connected switches have a first and second ends, the first end is connected serially to said power supply and the second end is serially connected to said elevator safety circuit bypass detector having two ends, one end of said elevator safety circuit bypass detector is connected serially to the second end of said serially connected switches and the second end of said elevator safety circuit bypass detector is connected to a second point terminal, said second terminal is connected to an electrical load for moving an elevator car;
