Electrical overload cut=out - has spring loaded toggle lever arrangement on cross piece carrying upper moving contacts

摘要

The electrical overload cut-out has upper contacts (1) which are lifted from lower contacts (2). An electromagnetic release (9) which lifts an arm (11) which in turn raises a vertical contact carrier (12) has a cross member carrying the upper contacts. This acts against a toggle lever arrangement supported above the cross member. This has a shallow U shaped piece (16) to the ends of which are secured by hinge pins (6) two levers (5) with pins (7) which slide in a slot in an upper member (4) attached to the switch traverse (3). A hairpin shaped spring (8) between the levers, holds their pins at the ends of the slot (4a).
