Abstract
An anti-rebound latch having a generally U-shaped housing which defines a central blade path opening between first and second side legs. The housing supports a pivotally mounted generally crescent shaped drive-arm which includes a kicker portion at one end positioned adjacent the top of the blade path opening and a pusher portion at its opposite end. The drive-arm is operatively associated with a blade catcher carried by the first side leg which is reciprocally movable between a first position in which no part of the blade catcher extends into the opening and a second position in which the catcher extends across the opening to the second side leg. The catcher is spring biased to its first position. The opposite side leg may carry a pole face which attracts the catcher in response to the blow-open movement of a contact blade within the opening which hits the kicker portion of the drive-arm causing pivotal movement of the drive-arm which results in the pusher portion of the drive-arm sliding the catcher into the blade path opening towards the second side leg. As a result of electromagnetic forces generated, the pole face attracts the catcher toward its second position which prevents …
