The invention concerns a control and monitoring device for a switch machine of a railway switch. The device comprises a power supply providing a switch motor with a current. The switch motor is adapted to move points of the railway switch. The device includes a relay having a primary contact connected to the power supply and a secondary contact connected to the switch motor. The relay is adapted to switch on and off the power provided to the switch motor. A current sensor is adapted to sense the current to be provided to the switch motor between the power supply and the relay. A voltage sensor is adapted to sense a voltage provided to the switch motor. A monitoring module is connected to the current sensor and voltage sensor, to record the measured current and voltage values.
