FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in non-contact thyristor switches for switching incandescent lamps. It comprises, in each phase, pairs of anti-parallel diode (4-6) and thyristor (8-10), control input of which through resistor (15-17) and closing contact (20-21) is connected to cathode, connected in series to incandescent lamps (1-3), connected by second outputs to star, wherein pairs diodes have same direction. Novelty is that neutral wire includes similarly directed pair of anti-parallel diode (7) and thyristor (11), control input of which through resistor 14 and control contact 13 is connected to cathode.
EFFECT: technical result consists in simplification of device and improvement of reliability by reducing number of thyristors and increasing service life of lamps.
