适用范围：1 ScopeThis part of IEC 60669 applies to manually operated general purpose switches, for a.c. onlywith a rated voltage not exceeding 440 V and a rated current not exceeding 63 A, intended forhousehold and similar fixed electrical installations, either indoors or outdoors.For switches provided with screwless terminals the rated current is limited to 16 A.Switches covered by this standard are intended for the control in normal use of:– a circuit for a tungsten filament lamp load; or– a circuit for a fluorescent lamp load (including electronic ballast); or– a circuit for a substantially resistive load with a power factor not less than 0,95; or– a monophase circuit for motor load with a rated current up to 10 A and a power factor notless than 0,6; or– a combination of these.NOTE 1 An extension of the scope to switches for rated voltages higher than 440 V is under consideration.NOTE 2 An increase of the rated current of 10 A for motor load is under consideration.NOTE 3 For the time being, switches with a rated current more than 10 A are considered as a 10 A current formotor load switch.The standard also applies to boxes for switches, with the exception of mounting boxes for flushtype switches.NOTE 4 General requirements for boxes for flush-type switches are given in IEC 60670.It also applies to switches such as:– switches incorporating pilot lights;– electromagnetic remote control switches (particular requirements are given in the relevantpart 2);– switches incorporating a time-delay device (particular requirements are given in therelevant part 2);– combinations of switches and other functions (with the exception of switches combined withfuses);– electronic switches (particular requirements are given in the relevant part 2);– switches having facilities for the outlet and retention of flexible cables (see annex B);– isolating switches (particular requirements are given in the relevant Part 2).NOTE 5 The minimum length of the flexible cable used with these switches may be governed by National WiringRules.Switches complying with this standard are suitable for use at ambient temperatures notnormally exceeding 25 °C, but occasionally reaching 35 °C.NOTE 6 Switches complying with this standard are suitable only for incorporation in equipment in such a way andin such a place that it is unlikely that the surrounding ambient temperature exceeds 35 °C.In locations where special conditions prevail, such as in ships, vehicles and the like and inhazardous locations, for example where explosions are liable to occur, special constructionsmay be required.
