Abstract
1. Operating mechanism for a circuit breaker, in which a control handle acts on a sprung contact lever (1; 20) by means of a ratchet lever (4; 23) and with the help of a bar (8) pivoted thereto forms a latch with the ratchet lever, characterised in that the ratchet lever (4; 23) and the contact lever (1; 20) are pivotable as a pre-assembled unit about a common axis (5; 24) fixed to the housing and the ratchet lever (4; 23) acts in the contact closing direction on the contact lever (1; 20) by means of a leg spring (6; 25), and a separately supported release lever (11) is provided for unlatching.
