Key Tronic switch parts
Key Tronic are not known to have ever sold switches separately. However, the following part numbers have been recovered from service manuals.
Most types are referred to as “actuator assembly” (“ACTUATOR ASSY”), and it is not specified whether they are reed or capacitive types. Both can occur in the same keyboard. 60-0003-01 (“SWITCH,REED:SPST”) has a quantity of 72 in the Tektronix 4023 service manual, suggesting that it is single unit; the service manual diagram draws some as single-unit and others as column-high or row-wide blocks, possibly for expedience when drawing the illustration. Alongside those 72 switches are two each of 61-0021-03 (single-unit actuator assembly) and 61-0261-09 (single-unit 9 oz alternate action actuator assembly), with different nomenclature (actuator assembly versus reed switch) and separate numbering ranges.
