Lock mechanism for e.g. circuit breaker, has springs implementing pressure support of each movable contact on fixed contacts fixed in displacement rod and/or elastic deformation rod

摘要

The mechanism (3) has movable contacts (13) cooperating with fixed contacts (12), where the mechanism is movable between a locked closing position and an unlocked open position of lines controlled by an electric apparatus. Each movable contact is rigidly connected to a contact carrier (4). Springs (16) implement pressure support of each movable contact on the fixed contacts fixed in a displacement rod and/or elastic deformation rod.
