<p>A snap-in panel mount circuit breaker has a case and a locking dog means including a rigid member with a cammed outer surface mounted in the case. A first set of lugs extends from opposite sides of the rigid member and are disposed in cooperating pivot openings in the case to form a pivot axis about which the rigid member is moveable between a first position, in which the rigid member projects outwardly of the case, and a second position, in which the rigid member is disposed substantially flush with the case. A second set of lugs extends from the rigid member in spaced relation to the first lugs. The second lugs are disposed in a guide channel in the case to define the arc of rotation of the rigid member about the pivot axis. A bias spring contained in the case engages the locking dog means to normally urge the locking dog means towards the first position.</p> |
