In a method for the production of a switch diamond for switch rails and double crossovers with a switch diamond point out of carbon steel and connector rails, the switch diamond point is rolled and submitted to heat treatment, by which the switch diamond point is transformed over its total cross-section into a fine pearlite texture, whereby subsequently the switch diamond point is tempered and at least in the area where the wheels roll over, a material removing treatment for the removal of the wheel zone texture different from the fine pearlite texture is put underneath and afterwards the switch diamond point is welded to connector rails, so that the production of a switch diamond is simplified and heat treatment in a conventional apparatus is made possible.
