Switch with a fixed set of contacts and a movable set of contacts. The fixed set of contacts comprises at least one pair of fixed contacts arranged a distance apart and each having an auxiliary contact part and a main contact part. The movable set of contacts comprises at least one auxiliary contact element and a main contact element, which, when the switch is closed, are in contact, under mechanical pre-stress, with the surface of the auxiliary contact part and of the main contact part of the pair of fixed contacts and bridge the distance between the free end edges thereof facing one another, the various features being such that when the switch is closed the auxiliary contact element and the main contact element make contact more or less simultaneously with the auxiliary and with the main contact parts of the pair of fixed contacts.
