Method and arrangement for providing a magnetic switch arrangement comprising a first magnetic system, a second magnetic system and a magnetic switching element. The first magnetic system ( 24 ) is arranged for biasing the magnetic switching element ( 18 ) and the second magnetic system ( 25 ) is arranged to interact with the biasing magnetic field from the first magnetic system at the magnetic switching element so that the magnetic switching element is in a predefined state. The second magnetic system ( 25 ) includes two equally polarized permanent magnets ( 4, 5 ) positioned at a predefined distance apart. An advantage of the method and arrangement is its provision of a magnetic switch arrangement which shows an improved tolerance towards deviations in the magnetic field of the permanent magnets.
