Editing Clare-Pendar Series S840 (section)

==Variants==
No documentation has been recovered for Series S840 beyond details of modification codes. No switches have been found for sale to the public with a known part number, and switches for sale business to business do not include illustration.

A specific variant was previously sold on eBay with NSN 5930-01-089-6772; this NSN indicates S84010, but the images of it (below) show an adapted switch. Clare-Pendar documentation indicates that modification K2 is the "Castillated [sic] S840 support lid", as shown in the photos. Sadly the documentation that accompanied those switches is now lost, and the specific part number cannot be recovered.

Per [[Clare-Pendar]] practice, the following codes are appended to the part numbers to customise the switch.
