Provides additional requirements applicable to rotary, manually actuated control switches, with definitions and terms useful in stating desired properties of design or performance. Includes clauses for rotary control switches which are not manually actuated. Does not apply to rotary switches that are not control switches; such rotary switches are covered on other IEC Publications, e.g. Publications 292-1 "Direct on line (full voltage) a.c. starter", 292-2 "Reduced voltage a.c. starter: Star delta starters" and 408 "Low voltage air break switches, air break disconnectors, air break switch disconnectors and fuse combinations.".
