The invention relates to a device to be integrated with to a manual switch stand, particularly for use in dark territory. The device secures the spindle of the switch stand against rotation, thereby preventing authorized throwing of the switches. The device also contains sensors that will clearly indicate to an external observer both the position of the switch points and the locked or unlocked status of the switch stand. A particular sequence of steps must be taken before an operator will be able to unlock the switch stand and throw the switch, and further steps are required before he can secure the switch stand and remove his key. The switch stand must therefore be left in a locked state, and it continuously indicates the status of the switch stand to a remote monitor.
