ABSTRACT:
A tilt latch for a window sash including a base member mountable on a sash and a slide member disposed for sliding movement in a channel formed in the base member and resiliently biased toward an extended position in which a nose-shaped first end of the slide member engages a window frame to prevent the sash from tilting out of the frame. A downward projection formed on a second end portion of the slide member interferingly engages an end edge of the base member to arrest movement of the slide member at the extended position, but this second end portion of the slide member is dimensioned to enable the projection to be lifted manually out of such engagement so that the slide member can be moved beyond the extended position.
