Publication number: 20250092716Abstract: A key cam according to certain embodiments generally includes a shell, a lost motion driver, a plug, and a lock control lug. The shell extends along a longitudinal axis defining a proximal direction and an opposite distal direction. The lost motion driver is rotatably seated in a proximal end portion of the plug, and is operable to rotate the shell with lost rotational motion. The plug is rotatably seated in the shell and includes a proximal bowtie opening and a distal bowtie opening. The lock control lug is movably seated in the shell and projects into a lock control opening of the shell.Type: ApplicationFiled: December 4, 2024Publication date: March 20, 2025Inventors: Kenton H.
