A guiding system includes a support on which a door leaf can be mounted; a support guide rail; and a guiding device by which the support is movably mounted or can be movably mounted on the support guide rail. The guiding system includes a switch device and/or a sensor or an interface for securing the switch device and/or sensor. The switch device and/or sensor is/are designed to generate a signal by which the power supply to an electric device can be interrupted and/or released. The switch device and/or sensor or interface is or can be positioned relative to the support guide rail such that the switch device and/or sensor can be switched and/or triggered in a specified position of the support, and thus the door leaf, relative to the support guide rail. The specified position is preferably an end position of the support relative to the support guide rail.
