19 PUSH BUTTONS AND OPERATOR

—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.
