Claim:
1. A window system, comprising: a window frame; a first window sash slidably received within the window frame; a striker assembly including a striker plate extending transversely from the first window sash, and a release portion; a second window sash slidably received within the window frame; a limiter assembly coupled to the second window sash, the limiter assembly including a rotary element comprising an engagement portion with first and second surfaces and a detent biased toward the first and second surfaces; wherein the rotary element is rotatable to an engaged position, the engagement portion is aligned with the striker plate along a linear axis extending through the striker plate, where the engagement portion is positioned to engage the striker plate when one of at least one of the first and second window sashes is slid within the window frame to prevent further movement of the first and second window sashes, and in the engaged position the detent is engaged with the first surface; wherein the rotary element is rotatable to a disengaged position in which the engagement portion is misaligned with the linear axis extending through the striker plate, and the detent is engaged with the second surface and holds the rotary element in the disengaged position, allowing the striker plate to pass the engagement portion when one of at least one of the first and second window sashes is slid within the window frame; and wherein with engagement of the release portion against the rotary element, the detent is released from the second surface, and the rotary element is biased and reset from the disengaged position toward the engagement position.
