Key-actuated switching mechanism e.g. for triggering switching action in electromechanical switching module

摘要

A keying arrangement for actuating at least one switching module includes a housing (3) with opening (6) as well as a web (7) jutting downwards and having an end (8) which is of concave or convex configuration for interacting with the e.g. concave or convex shaped upper end zone of a first guide fin (13), the latter being rigidly joined to a first key (11) which is used for switching the first switch module (2).
