CK Series 16mm & 19mm Standard Size Keylocks

NKK Switches CK Series 16mm and 19mm Standard Size Keylocks are offered in high security levels designed to perform dependably in a variety of diverse applications. These high-security keylocks come in flat and tubular key styles. The Flat key is reversible for easier setting, and the tubular key must be pressed inward to actuate. The interior construction of these keylocks provides a seal for the contact area, and the epoxy-sealed solder lug terminals prevent the entry of flux and other contaminants. These keylocks are suitable for automation control, audio-video, broadcasting, industrial, and medical equipment.
