description	The invention relates to an operating mechanism for operating at least one contact. The operating mechanism comprises:- an operating rod linearly guided in a base frame for connection with a contact;- a contact spring for urging the operating rod to an open position;- a rod mechanism of two links;- a cam follower arranged at the middle hinge;- a cam arranged on a cam shaft;- a cam shaft lock for locking the shaft at a rotational position where the cam follower abuts the cam at the end of a closing section;- a closing spring relaxing when the cam follower runs over the closing section towards the opening section and wherein the closing spring has a pretension, when the cam shaft is in the locked position;characterized in thatthe profile of the opening section (13) is designed such that the cam follower (7) follows the profile of the opening section (13) when the operating rod (3) moves from the closed position towards the open position.wherein the profile of the opening section is designed 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.
