Abstract
The invention is a device for displacing a switch blade between a position on a stock rail and a position at a distance from the stock rail. The device has: a locking bearing coupled to the switch blade and connected to a locking catch via an axle; and a locking rod that guides the locking catch against a locking support coupled to the stock rail, locks the locking catch to the support, and then unlocks and guides it away from the locking support. The locking support is positioned on the side of the stock rail opposed to the switch blade and is connected to a thrust bearing that is arranged on a fixed superstructure component. The locking bearing is arranged on a component that at least partially follows the displacement, and the displacement motion is transferred from the locking bearing to the switch blade via a displaceable push rod.
