Abstract

The invention relates to a device for shifting switch rails (6) associated adjustably with stock rails (7) or mobile frog tongues in railroad switches, configured as a latch or vertical clasp closure, comprising locking catches (4) which are activated by means of a cam or slide rod (5a, 5b), and closure pieces (3) and tongue attachments (2), wherein each locking catch (4) is pivotably supported in a tongue attachment (2) and the switch rail (6) is connected detachably to the tongue attachment (2). An improved and simpler adjustment option is to be created for such a device. For this, the cam or slide rod (5a, 5b) is vertically height-adjustable via a multi-edge body (9) mounted detachably in both closure pieces (3).
