    Abstract - (Show below) - (Hide below)

    Establishes requirements and tests for manually operated general purpose switches with voltage not exceeding 440V and current not exceeding 63A for household and similar fixed electrical installations, either indoors or outdoors. The current is limited to 10A for switches provided with screwless terminals. Also applies to switches supplied with boxes, switches for mounting in boxes, switches incorporating pilot lights, electromagnetic remote control switches, switches incorporating a time delay device and electronic switches. Does not apply to circuit breakers for household and similar installations, to switches for appliances and to cord switches.
