This chapter in the scope of GB 16915.1 has been revised to the following: This section specifies the classification, anti electric shock protection, grounding measures, structural requirements, mechanical performance, and technical requirements for electrical performance of electronic switches and related electronic auxiliary devices for household and similar fixed electrical installations. This part of GB 16915 applies to electronic switches and related electronic auxiliary devices used indoors or outdoors for household and similar fixed electrical installations. This section is applicable to operating lighting circuits, controlling the brightness of lights (dimmers), controlling the speed of electric motors (such as exhaust fans), and electronic switches for other purposes (such as heating control). The rated voltage of these switches does not exceed 250 V AC and the rated current does not exceed 16 A. The above operations and/or controls are artificially achieved through starting elements, sensing surfaces, and sensing devices, using touch, proximity, rotation, light, sound, heat, or other influences. This section is also applicable to general purpose electronic switches with built-in automatic functions. The operation and/or control of such electronic switches is stimulated by changes in physical quantities, such as light, temperature, humidity, time, wind speed, human presence, etc. This section also applies to the installation box of electronic switches, except for the installation box of concealed electronic switches. This section also applies to electronic remote control switches (RCS) and electronic time delay switches (TDS), with a rated voltage not exceeding 440 V and a rated current not exceeding 25A, intended for indoor or outdoor use, household and similar fixed electrical installations. Note 1. Switches with only passive components (such as resistors, capacitors, inductors, PTC and NTC components, varistors, printed circuit boards, and connectors) are not considered electronic switches. Note 2: Electronic switches can have control circuits with AC or DC rated control voltage. Electronic switches that comply with this section are suitable for use in ambient temperatures typically not exceeding 35 ° C and occasionally reaching 40 ° C. Special structures may be required in places with special conditions, such as ships, vehicles, and similar locations, as well as in hazardous areas (such as areas where explosions may occur). Note 3. This section is not intended to cover devices designed for use in appliances, or devices delivered with specific electrical appliances, as well as devices within the scope of GB 14536 or GB 15092. The design examples and functions of electronic switches can be found in Appendix AA. Note 4: Electronic switches without mechanical switches in the main circuit cannot form a "fully open state". Therefore, the circuit on the load side should be considered live
Function of testing report:
