Abstract: In a device for checking the end positions of movable parts of a railway switch, in which at least one separate end-position checking device (5, 6) is assigned to each movable switch part (3, 4), wherein the end-position checking device (5, 6) includes a rod (8) and a checker housing (9) in which the rod (8) is inserted and in which at least one limit switch (21, 22) is arranged to detect the two end positions of the movable switch part (3, 4), the rod (8) in its portion reaching into the housing (9), or the housing (9), comprises at least two axially spaced-apart switching flanks for the actuation of the at least one limit switch (21, 22), wherein at least one of said switching flanks is arranged to be axially displaceable relative to the other of said switching flanks and fixable in the respective position.

Abstract: In a device for the remote monitoring of railway switch drives operated via four lines, for instance by three-phase current, or of a monitoring circuit operated via four lines and including electric contacts which are switched as a function of the position of the railway switch and via which, upon reaching of the respective end position in the switch tongue, a monitoring circuit is closed across said four lines, for a railway switch monitor fed, for instance, by direct voltage, wherein a plurality of checking planes arranged in an offset manner in the longitudinal direction of the rails are provided and in each checking plane at least four electric switching contacts are circuited together and cooperate with moved parts of the railway switch drive or railway switch, for instance a check rod, in a manner that in an end position of the switch tongue two electric switching contacts are each in the closed, and two electric switching contacts are each in the open, switching position and the switching position of e
