The invention relates to an insertion latch for an ejectable pull handle system for installation of electronic devices into rack mounted computer systems. In particular, the invention comprises an insertion latch that has a compression member and a tension member that are compressed and placed in tension respectively when a latching head of the insertion latch is displaced. The latching head moves to its rest or latched position by a combination of forces supplied by the compression member and attention member. The insertion latch also has a leaf spring mounted through a channel of a mounting portion of the insertion latch. The leaf spring contacts a force application surface on the ejectable pull handle and biases that ejectable pull handle toward an intermediate position. The force application surface of the ejectable pull handle is preferably semi-circular such that the force applied by the leaf spring is directed, for the most part, tangentially to the rotation of the ejectable pull handle, regardless of the position of that handle.
