Abstract
A circuit interrupter rotary contact arm is provided. Rotational torque is applied to the contact arm by a spring force from one or more springs arranged along the sides of the contact arm. The contact arm includes an edge surface having one or more features or bumps. The bumps are configured cause the one or more springs to exert increased spring force and to increase frictional resistance, which increases the rotational torque required to move the contact arm.
