摘要:
A bistable relay circuit adapted to be operated from a two polarity supply of a predetermined voltage, includes a control relay having a coil exhibiting hysterisis, and at least a first single pole, double throw switch, having one pole contact and two non-pole contacts. The control relay coil has a resistance value which is low compared to the resistance value of the first resistor, while a current operatively flowing therethrough is insufficient on its own to energize the control relay. A first resistor is in series with the coil of the control relay. The series combination of the control relay coil and of the first resistor are connected to the power supply. A steering relay has a coil and at least a second single pole, double throw switch, having one pole contact and two non-pole contacts. A single pole, single throw switch is in series with the coil of the steering relay. The series combination of the steering relay coil and the single pole, single throw switch is connected to the power supply. A second resistor is connected to the pole contact of the first switch, and to one of the non-pole contacts of the second switch, and a capacitor is connected to the pole of the second switch and to one polarity of the power supply.
