Abstract
A zero insertion force socket using normally closed contacts and three adjacently overlying plates. Upon lifting the activating arm, a cammed cylinder is rotated which pushes the middle plate and pulls the top plate to thereby open the prongs of the contact for component lead insertion therebetween. Upon the activating arm being moved back into its original position the cammed cylinder rotates and the middle plate shifts back to its original position under the influence of a contact prong closing about the component lead as the top plate shifts back to its original position under the influence of the cammed cylinder.
