ABSTRACT:
An improved window sash latch which has a locking mechanism and a keeper is provided with a handle that rotates from a “locked” to an “unlocked” position. An inner cavity of the handle has a spring assembly having a sliding part that can be forced into a detent as the handle slides around a cylindrical extension of an outer surface of the latch. The detents correspond to a “locked” and an “unlocked” position of the latch. The latch also provides two cams where both cams revolve relative to each other; one cam is activated by the handle through the handle's shaft, the other cam engages the keeper, and both cams engage each other.
