View source for User:Daniel beardsmore/Interesting part numbers

The following series names (as part number prefixes) and switch parts are of interest should they appear for sale. Note that most of these appear on stockist websites but that the stock levels on virtually all such sites in all countries are to some extent false, and many of these parts are taken from such sites and were found to not be sold. The switches below are either undocumented (but possibly observed) or are a mystery.

==Alps==
*[[Alps SKCC series]]
**SKCCAC
*[[Alps SKCL/SKCM series]]
**SKCLAC (was found on sale for $100/pc, MOQ 100 — sure I want to spend $10,000 finding out what SKCLAC is)

**SKCLJC — [[Alps SKCL Lock]]
*Uncertain
**SKFNAA
*[[Alps SKFR/SKFS series]]

==Clare-Pendar==
Clare-Pendar and CP Clare parts. The formatting of these varies, e.g. "S840-10K2" or "S84010 K2"

===Series S820===
[[Clare-Pendar Series S820]] is a tall reed switch. Part numbers begin S820.

Listed examples:

*S820-10 (NSN 5930-00-175-7423, 5930-01-012-6279)
*S82010B5C8 (NSN 5930-01-025-9223)

*S82010J7 (NSN 5930-01-025-9223; J7 is illuminated)

Mod C8 is listed as "(spare)" and mod B5 is listed as "Not to be used".

===Series S840===
[[Clare-Pendar Series S840]] is a medium height metal contact switch. Part numbers begin S840 (momentary) and in theory S841 (alternate action) and S842 (alternate action, latching).

====Known examples====
Seen for sale:

*S840-10 (NSN 5930-00-603-7158, may in fact be S84010 K2)
*NSN 5930-01-089-6772 (officially S84010; should be S84010 K2)
*S840-10K2 (NSN 5930-01-051-1280)

====Theoretical parts====
Theorerical part numbers for observed switches:

*S84020 E9
*S84010 H3

===Series S880===
[[Clare-Pendar Series S880]] is a medium height reed switch. Part numbers begin S880 (momentary), S881 (alternate action, never seen) and S882 (alternate action, latching).

Listed examples:
*S880-10 (NSN 5930-01-123-8586, could be J7 mod)
*S88010J7 (also NSN 5930-01-123-8586; J7 is illuminated)

==Ericsson==
*RMD 973* — [[Ericsson RMD 973 series]]

==Futaba==
*MA* ([[Futaba MA series]]) — MA41JF is the only known model number from this series, and known sub-series are MA41, MA42, MA71 and MA72
*MD* ([[Futaba MD series]]) — MD-4PCS is the only known model (already purchased), and sub-series are MD-4P and MD-7 (illuminated)
*MR* ([[Futaba MR series]]) — [[Futaba MR-6C series]] is the only known MR sub-series
*ML* ([[Futaba ML series]]) — ML-3-CM is the only known model (already purchased), and ML88 is the only known sub-series

==Marquardt==
*6180.* — [[Marquardt Series 6180]]
*6184.* — [[Marquardt Series 6184]]

==Mechanical Enterprises==
*T-5* — [[MEI T-5 series]] (known subfamilies: T-5C, T-5H, T-5S, T-5L); example: T-5C-A-NO (T-5C, alternate action, normally open)

==Omron==
*B3G* — [[Omron B3G series]] (not knowingly seen)
*B3G-S* — [[Omron B3G-S series]] (widely known but no attempts to match known part numbers to actual switches has succeeded yet)
*B2R-* — [[Omron B2R series]] (excluding B2R-G1, B2R-M, B2R-M1 and B2R-ME1, all of which are already acquired; B2R-ME is needed in better condition)

==RAFI==
Note that the centre dot was added later. Most types will end "/0000" (no LED) which may erroneously be written "0000" without the slash.

*3.12960.* — [[RAFI RS 74 M]] alternate action
*3.17960.* — [[RAFI RS 74 M]] illuminated
*3.13.011.* — [[RAFI RS 76 C]] IP65

Part numbers for [[RAFI RS 74 C]] are not known, but that series is especially desirable as it has yet to be seen.
