Abstract

The overcurrent protective switch contains a switch lock 8, which, in the switched on position, holds the movable contact pieces 3 in engagement with the fixed contact pieces 2 against the force exerted by at least one switch-off spring. The switch lock 8 comprises a switch splicing plate 10 connected to the movable contact pieces 3 in an articulated mechanism; a toggle lever splicing plate 12 connected to the switch splicing plate 10 at a toggle joint 13; and a pawl lever 15 mounted in a position inside the housing 1, which is supported by a trigger pawl 17 and connected with the toggle lever splicing plate 12 in an articulate mechanism. The joint axles 11, 13, 16 of the switch splicing plate 10 and the toggle lever splicing plate 12, as well as the pivot bearing axle 14 of the pawl lever 15 are in the on state arranged on a slightly curved line, so that a past dead center condition is created. Under this condition, the toggle joint 13 is supported against a latched stop slide 22, the latching of which is released when switched off manually. The pawl lever 15 is capable of swiveling in both directions, that is, in one direction when the trigger pawl 17 is actuated, and in the other direction when switched off manually. Thus, a quick switching off is achieved either manually or by a current surge, using only a few simple components.\!
