Abstract

The rest contact bridge (4) is integral with a moving element (20) which also holds, but via elastic means (25, 26) and hooks (31, 32), a working contact bridge (5), the movement of which is normally caused by the unbalance of dead point passage devices (7, 8); pivoting means (9, 10) displaced by the pusher (3) on which are bearing the devices (7, 8), cause a forced lifting of the rest cntact bridge (4) by operating a compression of the elastic means (25, 26) when the work contact bridge is closed. This switch, which enables to perform important opening strokes of the rest contact bridge, is conveniently used in apparatuses wherein said stroke was shorter with another switch.
