A device for indicating a multi-position state and having one or more sensors, one or more bi-stable, magnetic switches, and a control unit. The switches are provided with an electromagnet arranged in connection with each individual switch thereby enabling the switches to be switched between two or more indicating positions by sending an electric pulse through the electromagnet. The sensors are connected to the control unit, which is in turn connected to the switches. The sensors are arranged to sense which of the two or more positions is the current state of a measured object, and transmit a signal corresponding to the position of the measured object to the control unit. The control unit is arranged to transmit a signal to the electromagnet of the corresponding switch in order to update the indicated state of the switch.
