    Abstract: Disclosed is a railroad switch device for moving railroad switch points. The device includes two spring assembly sets placed over two switch operation rods. The spring assembly sets move railroad switch points and keep railroad switch points against a stock rail. At least one sensor is mounted adjacent to two switch operation rods. The switch operation rods have a switch point position target connected to the switch operation rods. The switch point position target follows a movement of two throw rods. The two spring assembly sets provide a spring holding force to the two switch operation rods. The spring holding force provides a safe operation of a switch point position assembly by at least one of determining that the spring holding force is present in the moving railroad switch point, and pushing the spring holding force towards the switch point position assembly away from the at least one sensor.
