Abstract
A method and a system for checking the correct rail position of a guide member of a guided vehicle. The system is based on the use of an electrical switch designed to cooperate with a guide member of the vehicle guided by at least one guide rail. The switch has two states, respectively a first state and a second state. In one of the states the electrical switch is open and in the other state the electrical switch is closed. The switch is mounted on a load-bearing structure such that it is able to interact with the guide member. The switch is able to switch from the first state to the second state by interacting with at least one part of the guide member.
