Footnotes

  1. Trigger action mushroom heads are tamper proof in that a change of contact state is not possible by teasing or floating the operator. For emergency stop applications, always use a trigger action push button (per EN/IEC 13850).
  2. Other key numbers:
    —key no. 421E: add the suffix 12 to the catalog number.
    —key no. 458A: add the suffix 10 to the catalog number.
    —key no. 520E: add the suffix 14 to the catalog number.
    —key no. 3131A: add the suffix 20 to the catalog number.
    Example: The catalog number for a Ø 40 mm red mushroom head for a trigger action, maintained push button, with release by
    key no. 421E becomes: ZB5AS94412.
