Abstract

An electrical switch (50) has two contact points. Each of these contact points has a fixed contact element (12) and a moving contact element (12) which interacts with said fixed contact element (12) and is fitted on in each case one contact lever (13, 61) which moves in a pivoting manner, said contact elements (12) being coupled to one another by means of a drive rod (17). The contact lever has a stop (23) allocated to it, against which the contact lever rests during switching off and about which the contact lever is rotated during switching. If the ratio between the distance between the moving contact element and the stop to the distance between the stop and the point at which the drive rod acts is greater than 1.5, especially 2, the moving contact element moves quicker than the drive rod which is driven by the contact lever. Such a switch is used, for example, in the case of auxiliary switches or neutral-conductor isolators which can be assigned to a line protection circuit breaker. <IMAGE>
