HJFC-1161212

1. What this is

HJFC-1161212 is an OTTO switch — series not recognized.

2. Part-number decode

• Series: OTTO OTTO (series not recognized)
• Configuration code: the digits after the dash (e.g. the 1161212 group) encode the exact actuator, contact arrangement, termination, and cap/color per OTTO's datasheet — not derivable from the part number alone

3. Compatibility & ordering

OTTO switches are rugged, sealed electromechanical pushbuttons for commercial, military, and aerospace use. Match by series (size/style — P1 full-size, P3 regular, P8 compact, P9 dome, P7 subminiature, P5 alternate-action), action (momentary vs latching), and illumination, then use OTTO's datasheet to confirm the exact contact/terminal/cap configuration encoded in the numeric part of the code.

4. Data-quality note

The exact OTTO series/configuration could not be confidently decoded from this part number. It is kept and documented (not deleted) and flagged needs-verification rather than guessed.
