Applies to control circuit devices and switching elements intended for controlling, signalling and interlocking of switchgear and controlgear having a rated voltage not exceeding 1000 volt a.c. (at a frequency not exceeding 1000 Hz) or 600 V d.c. Provides special requirements for indicator lights and control switches with positive opening operation. This Standard is identical with and reproduced from IEC 60947-5-1:1997 including the Amendment 1:1999 and Amendment 2:1999.

This part of IEC 60947 applies to control circuit devices and switching elements intended forcontrolling, signalling, interlocking, etc., of switchgear and controlgear.It applies to control circuit devices having a rated voltage not exceeding 1 000 V a.c. (at afrequency not exceeding 1 000 Hz) or 600 V d.c.However, for operational voltages below 100 V a.c. or d.c., see note 2 of 4.3.1.1.This standard applies to specific types of control circuit devices such as: manual control switches, for example pushbuttons, rotary switches, foot switches, etc.; electromagnetically operated control switches, either time-delayed or instantaneous, forexample contactor relays; pilot switches, for example pressure switches, temperature sensitive switches (thermostats),programmers, etc.; position switches, for example control switches operated by part of a machine ormechanism; associated control circuit equipment, for example indicator lights, etc.NOTE 1 A control circuit device includes (a) control switch(es) and associated devices such as (an) indicatorlight(s).NOTE 2 A control switch includes (a) switching element(s) and an actuating system.NOTE 3 A switching element may be a contact element or a semiconductor element.It also applies to specific types of switching elements associated with other devices (whosemain circuits are covered by other standards) such as: auxiliary contacts of a switching device (e.g. contactor, circuit breaker. etc.) which are notdedicated exclusively for use with the coil of that device; interlocking contacts of enclosure doors; control circuit contacts of rotary switches; control circuit contacts of overload relays.Contactor relays shall also meet the requirements and tests of IEC 60947-4-1 except for theutilization category which shall comply with this standard.This standard does not include the relays covered in IEC 60255 or automatic electrical controldevices for household and similar purposes.The colour requirements of indicator lights, pushbuttons, etc., are found in IEC 60073 and alsoin publication 2 of the International Commission of Illumination (CIE).The object of this standard is to state:a) The characteristics of control circuit devices.b) The electrical and mechanical requirements with respect to:1) The various duties to be performed.2) The significance of the rated characteristics and of the markings.3) The tests to verify the rated characteristics.c) The functional requirements to be satisfied by the control circuit devices with respect to:1) Environmental conditions, including those of enclosed equipment.2) Dielectric properties.3) Terminals.
