Korry Spare Switches for the Boeing 777

In coordination with Boeing, in 2011 Esterline released a new version of the Korry switch originally installed on 777 aircraft. The new configuration has a one-piece cap/switch module (refer to CMM 31-12-02 for mounting differences). The part-numbering system was also updated. The new cap/switch module is fully interchangeable with the original assemblies and compatible with original mounting hardware.

For part-number correspondences, consult the table below.
