If connecting element component has other all element constructions of what a proper curved bar and connecting element component Into substantially straight, but at least it is configured to without prominent angle, this is especially preferred in this connection.There is provided one accordingly Device is planted, its changing from a stationary state to next stationary state can come real particularly simply and with especially small failure danger It is existing.

Connecting element component is equally particularly preferred that, it so interacts so that in handoff path with spring energy storage device The dead point of spring energy storage device is crossed during track switch.Thus this especially realize, i.e., from the first stationary state, (such as tongue is abutted in State at stock rail) into the handoff procedure of the second stationary state (such as state of the tongue away from stock rail), in slide bar The power of the spring energy storage device of preferred pretension is overcome to realize the motion of connecting element component in first motion path, and in middle shape By dead point in state, therefore the point for the maximum compression for passing through spring energy storage device, and it is last in stationary state to be reached The remaining motion of slide bar is realized using the support of spring energy storage device, therefore a kind of dress is created using particularly simple device Put, it can reliably keep two kinds of desired stationary states by means of unique spring energy storage device.

Thus, if connecting element component is fixed on the sleeper of track between the tongue of rail switch, this is same Sample is preferred.Ensure accordingly the apparatus according to the invention persistently and it is mobile reliably rested in rail switch it is desired At place.The single element of the apparatus according to the invention is avoided relative to one in tongue or one in stock rail simultaneously Change its position limited in advance.
