ABSTRACT:
A lever mechanism for the insertion and removal of a module in a housing includes two levers the proximal ends of which are pivotally mounted to the module at spaced locations on the module. The distal ends of the levers are disposed in confronting relationship when the levers are longitudinally aligned. A leaf spring is longitudinally slidably mounted to the levers including sliding attachment to the levers at their distal ends. The leaf spring is sufficiently stiff to maintain spatial alignment of the distal ends of the levers during angular movement. Arcuate sectors branching from the levers adjacent their distal ends overlap and provide handles for manually operating the levers. Latches correspondingly positioned at the proximal ends of the levers cooperate with catches in the opening or slot in the housing in which the module is inserted to provide the final insertion or removal forces for insertion and removal of the module with respect to the housing.
