An actuator for a window lock including a housing on the window frame, a link operatively connected to a window lock, and a control member. The link includes a spur gear with an annular surface having a number of annularly spaced teeth, and the control member includes a ring gear with an annular inner surface having a number of recesses defined therein for receiving a plurality of teeth. The spur gear is pivotable about a first axis and the ring gear is pivotable about a second axis parallel to but offset from the first axis. Portions of the link and the control member engage to pivot the link about a first axis during selected pivoting of the control member, and a pivoting force applied to the link to move the window lock from a locked to an unlocked position causes at least one of the link teeth to bite into the control member annular surface and prevent pivoting of the link about the first axis.
