Abstract (en)

[origin: WO2020064277A1] The invention relates to a contact arm (1) and a relevant method for a disconnect switch, having at least one profile body (2) and at least one contact element (3), which is in electrical contact with the at least one profile body (2) and is designed to establish electrical contact with a contact counterpart. The at least one profile body (2) has a first diameter d parallel to the at least one contact element (3). The at least one contact element (3) has a concave surface which has a radius of curvature r' and is arranged on a side which is directed away from the profile body (2), wherein the radius of curvature r' is smaller than the radius of curvature r of a circle segment having the first diameter d of the at least one profile body (2). The method comprises electrical contact being established in respect of the contact arm (1) of the disconnect switch, wherein a contact element (3) of the contact arm (1) establishes electrical and/or mechanical contact with a contact counterpart, wherein a concave surface of the contact element (3) which is directed towards the contact counterpart has a radius of curvature r', which is smaller than the radius of curvature r of a circle segment having the maximum diameter d' of the contact element (3).
