Abstract
The invention concerns a disconnecting appliance, such as a switch, a fuse-disconnecting switch or breaker-reversing switch, having a novel arrangement of fixed and moving contacts promoting contact surface self-cleaning and increasing contact force for the same contact force applied by the cam. Moreover, it comprises a newly designed cam for actuation the mobile contacts to optimize to the maximum the operating conditions when engaging and releasing. The appliance is characterized in that the moving contacts (,) comprise two contact surfaces (,) arranged in substantially perpendicular planes, corresponding with those (,) of the fixed contacts (,′ and,′), each moving contact (,) moving in radial translation relative to the control shaft (,) along a direction (F) substantially perpendicular to a straight line passing through its two contact surfaces (,). The cam (,) comprises a flow track (,) and a return track (,), respectively corresponding to engaging and releasing, to guide a driving pin (,) integral with a moving element (,) coupled to the moving contacts, the moving element being arranged to be translated radially relative to the control shaft (,). The invention is applicable to any industrial electrical installation.
