FIELD: electricity.
SUBSTANCE: invention relates to the contact system of auto-switches operating in the electric drive mechanisms of railway automatics and telemechanics. The contact system contains switching levers, working levers, knife blades with floating roller knives, spring pads with asymmetric contact springs, which ensure the rotation, when they hit roller blades and transmit a signal for position control and motor control.
EFFECT: increasing the reliability of the switch electric drive.
