A casing is secured in the housing and has a passage for receiving and exactly guiding the latch to engage into the door frame. A spindle is slidably engaged in and actuated by the coil and coupled to either of the pegs for rotating the follower to actuate the latch. An enclosure is secured in the housing for receiving the coil. A spring may be used to bias the spindle toward the follower.
