Abstract
A circuit breaker is disclosed, in particular for low voltages, having a switch shaft and a contact lever rotationally mounted and extending transverse to the longitudinal axis of the switch shaft and protruding out of the switch shaft, the shaft carrying a movable contact on a side of the outer contour of the contact piece, and including a recess on the opposite side of the outer contour thereof for suspending a pin having a force applied thereto on both sides of the contact lever by way of one spring each, each applying a torque to the contact lever in the closing direction. The two springs each include a cover element extending along the spring and each disposed between the spring and the arc formed between the contact pieces when the circuit breaker is opened.
