Contact device for a switch

A contact device in a switch, in particular in a circuit breaker, having

• a movable contact lever under spring pressure, which on one end includes a contact point for an associated fixed contact element and on its other end is pivotally supported on pin means of a tripping system which when tripped displaces said pin means in a direction transverse to the longitudinal direction of said contact lever,
• a stop for the contact lever being disposed between the two ends in order to pivot the contact lever about the stop upon a displacement of said pin means and thereby to disengage its contact point from the fixed contact element, said stop having at least two contact locations for the contact lever, which locations are spaced apart from the contact lever and from its supported end by different amounts, in such manner that the contact lever, beginning at its position in which its contact point rests on the fixed contact element, upon displacement of its supported end first comes into contact with the contact location, which is the most remote from the supported end and then, before the termination of the displacement, comes into contact with the contact location of the stop, which is located closest to the supported end, and
• a compression spring supported on a housing element and acting upon the contact lever at a point located between the end of the contact lever supported on said pin means and the contact location of the stop located closest to said end.
