C&K Component Intelligence

Yes. The official C&K brand site states that C&K is now part of Littelfuse and that C&K switch products have moved to the Littelfuse catalog.

PartGenie provides a searchable C&K manufacturer catalog when source catalog data is available; this hub is the intelligence and navigation layer for understanding product families, sourcing risks, lifecycle checks, and comparison paths.

Compare mechanical footprint, actuator style, mounting method, terminal type, contact rating, voltage/current limits, operating temperature, cycle life, and accessory requirements. Avoid assuming two switches are interchangeable because they share a product category.

Usually no. For electromechanical switches, the stronger decision terms are mechanical compatibility, electrical rating fit, accessory compatibility, and functional alternative. Datasheet drawings and qualification tests are essential.
