Abstract
An operating mechanism for operating at least one contact is provided. The operating mechanism includes a base frame and an operating rod that is linearly guided in the base frame for connection with at least one contact. The operating mechanism further includes a contact spring for urging the operating rod to the open position and a rod mechanism having two links, and each link has a first end and a second end. The operating mechanism also includes a cam follower arranged at the middle hinge of the rod mechanism, a cam arranged on a cam shaft, a cam shaft lock for lacking the shaft, and a closing spring. The opening section of the cam is configured such that the cam follower follows the profile of the opening section when the operating rod moves from the closed position towards the open position.
