Abstract: A retractor element includes a rigid slide connected between a latch bolt and a solenoid plunger for movement between a first position and a second position, the slide operably connected to plunger. A pivoting link defines a slot having an inner end portion extending transversely, the slot configured for pivoting the link when the slide moves between the first position and the second position of the slide. When the retracting mechanism is energized the plunger retracts causing movement of the slide to the second position of slide and the pin to enter the transverse end of the slot in the link. A bearing surface intersects the path of movement of the pin such that significantly less current is required for retaining the plunger in the retracted position than to retract the plunger for blocking the return of the latch bolt to the projected position.

Abstract: A sensor assembly for generating a request to exit (REX) signal for a door lockset operable with a latch operator and a controller that can signal an alarm. In one embodiment, the sensor assembly includes a mounting member adapted to be in a fixed position in the door lockset, a rotatable member adapted to rotate in response to rotation of the latch operator, and a sensor mounted to the mounting member. The sensor is spaced from the rotatable member and is configured to detect rotation of the rotatable member. When the rotatable member is rotated corresponding to rotation of the latch operator, the sensor detects the rotation, and a switch in the sensor, which may be magnetic, is actuated, closing a circuit to send a REX signal to the controller. The sensor assembly may be associated with a chassis of the door lockset.
