Differential switch for e.g. electrical installation, has automatic power cut-off conductive branch extending along direction transversal to rotating contacts axle, and automatic power cutoff conductive blade placed relative to branch

摘要

The switch has an automatic power cut-off conductive branch (10) that extends along a direction transversal to a rotating axle (8) of a rotating contact (2). An automatic power cut-off conductive blade (7) connected to the contact is placed relative to the branch. The blade is placed such that it is placed against and spaced apart from the branch when the contact is in closed and open positions, respectively.
