Brain KB-9001S (possibly KB-9001 S) is a keyboard with TEC switches.
The label reports the FCC ID as "ISNJK-168/268/RB88". This is in fact a combination of two listed IDs (ISNJK-168 and ISNJK-268, both with a final action date of November 1990) plus one unlisted ID of ISNJK-RB88.
A combination of white and yellow TEC switches are used; yellow appears to be a heavier switch, as it is used for space and enter.
