Abstract
The electronic access control strike can have a bolt socket, a bolt path leading to bolt socket, a keeper movably mounted to a frame in a manner to be moveable into and out of interference with the bolt path, a cam member moveable for selectively blocking or unblocking the movement of the keeper, and an anti-preload member which is moveable into interference between the keeper and the cam member for preventing the keeper from conveying a preload force onto the cam member when the cam member is in the blocking position, and moveable out from interference between the keeper and the cam member when the cam member is in the unblocking position to allow the keeper to be moved out from interference with the bolt path.
