RAFI RS 74 and RS 76 types list

German firm Meyer Industrie-Electronic GmbH has on their website a list of RAFI part numbers along with very brief descriptions. Unlike many such lists on many such sites, this list seems to be accurate, as known RAFI types correspond with the descriptions given. The list suggests that RAFI made significantly more full-travel keyswitch (RS 74 M, RS 76 C and RS 76 M) types than we are aware of. According to Meyer, the part numbers come from price lists.

One distinct type (not counting LED colours) exists that is apparently not listed, being 3.12.960.905 (RS 74 M SPDT alternate action). Until the seller confirms that the part number is correct (the switch is advertised as RS 76 M!) this is assumed to be a type missing from Meyer’s lists.

Considering that the orange diode types are marked with the batch or date code followed by β€œ2”, that would suggest that they are 3.13.005.002, and indeed there is such a part number waiting. (Looking for that part number is how this list came to be found.)

Sadly, there is no mention of RS 74 C anywhere.

Switches

The terminology is as follows (free translation in context):

M-einbautaster
Mechanical keyswitch
C-einbautaster
Contactless keyswitch
Taster
Momentary keyswitch (literally, β€œpushbutton”)
Schalter
Alternate action keyswitch (literally, β€œswitch”)
Leucht
Illuminated (from β€œbeleuchtet”)

Types marked β€œπŸ‘οΈβ€ have been observed. Types marked β€œπŸ“–β€ are only known from catalogues. All part numbers are normalised into the modern format (five digit groupings with subtype code).
