Abstract

Improvements in electrical circuit breakers, characterized by including: a) A support, b) at least one immobilized contact, c) at least one movable contact arm maintained oscillating in said support between the positions of open circuit and closed circuit with respect to said immobilized contact, d) means for oscillating said movable contact arm between said open circuit and closed circuit positions; said means comprise a first oscillating link connected to said contact arm, a second oscillating link pivotably supported in a bearing normally fixed in said support and both first and second links hinged together by a knee pivot, e) a movable operator member maintained in said support, f) means for actuating said angular linkage game between a collapsed situation and a rigid situation for moving said contact arm between said opening position and said closing position of the circuit, comprising spring-loaded elements acting between said operating member and said knee pivot, and g) means for supporting said immobilized contact in said support, which include adjustable spacer elements between said immobilized contact and said support to vary the separation of said contact with respect to said support.
