5.3.4 Electrical appliance group
When a group of electrical appliances of the sizes listed in 5.3.1 are installed side by side on the control panel, the distance a between the center lines of the same row of mounting holes and the distance b between the center lines of each row shall not be less than the values given in Table 5 unless otherwise specified by the manufacturer. Table 5 Minimum distance between the centers of mounting holes Preferred values Unit: mm
Distances a and b can be interchanged.
These values are intended to guide design. However, when it is necessary to install electrical appliances from different manufacturers, users should select interchangeable electrical appliances and ensure electrical clearance and electrical distance when the electrical appliances are installed and wired. Note: According to the provisions of the electrical appliance manufacturer, the installation distance of some electrical appliances can be less than the values listed in Table 5, depending on the design requirements, connection method, marking, etc. of the electrical appliances. In addition, some forms of electrical appliances may require a greater distance than the values listed in Table 5. 5.3.5 Installation category (overvoltage category)

Structural and performance requirements
Control switches shall comply with the requirements of this standard and be manufactured in accordance with drawings and technical documents approved by the prescribed procedures. 6.1 Structural requirements
6.1.1 Materials
6.1.1.1 The structural materials of the control switch shall meet the application requirements and meet the relevant test requirements after forming the product. The test can be carried out on the control switch and (or) the components of the control switch. For example: mechanical strength test, fire hazard test, comparative tracking index (CTI) determination of insulating materials, etc. Specific test items shall be specified in each product standard. For special reasons, it is allowed to replace the test on the control switch with the test on the pre-selected material. 6.1.1.2 Conductive parts shall be made of copper material, and the electrical contact parts shall be treated with corrosion or oxidation resistance. 6.1.1.3 Insulating parts shall be made of durable, flame-retardant, moisture-resistant and mildew-resistant materials, and toxic materials and materials that can release toxic gases shall be avoided as much as possible.
JB/T6317-2002
6.1.1.4Metal parts such as screws, nuts, pins and springs shall be made of corrosion-resistant materials or carbon steel treated with corrosion protection. Screws and other parts used for conducting electricity shall be made of copper. 6.1.2Connection terminals
7.1.7 of GB/T14048.1-2000 is applicable. 6.1.3Protective grounding
7.1.9 of GB/T14048.1-2000 is applicable. 6.1.4Casing
Protection type of control switch GB/T14048.12000 Appendix C is applicable. 6.1.5 Conditions for positive disconnection operation
In the effective part of a certain stroke of the control switch, the elastic element between its contacts and the force application point of the actuator has no elastic effect. 6.1.6 Conditions for control switches suitable for isolation Control switches suitable for isolation should be manually operated and have positive disconnection operation (see Appendix K of GB14048.5--2001), and should meet the isolation performance requirements in the disconnected position (see 2.1.19 and 7.1.6 of GB/T14048.1-2000). The disconnected position of the rotary control switch suitable for isolation should be the position that the switch can maintain when no operating force is applied. When the contact element is in the disconnected position, in order to avoid misoperation, measures should be taken to prevent the operation of the control switch suitable for isolation. This can be achieved by using a padlock or a locking device that can only be released with a special tool (or key). 6.1.7 Operating force (or torque)
The force (or torque) required to operate the actuator must be adapted to the specified purpose. Its value should take into account the size of the actuator, the type of housing or plate, the environment in which it is installed, and its specified purpose. The minimum operating force (or torque) should be large enough to prevent accidental operation. For example, for buttons used in waterproof housings, when the housing protection test is carried out, the buttons should be able to withstand the impact of water spray without malfunctioning. 6.1.8 Operating quantity of indicating switch
The operating value and return value of the operating quantity depend on the normal rising value and normal falling value of the operating quantity. The rate of change of the operating quantity should be regular and should not reach the operating (or return) value in less than 10s. Both the operating value and the return value can be fixed. Or one or both of them can be adjusted (or the difference can also be adjustable). The tolerance value of the operating quantity means that the indicating switch shall not be damaged or its characteristics shall not be changed. The maximum value of the tolerance value is higher than the highest setting value of the operating value, or the minimum value of the tolerance value is lower than the lowest setting value of the return value. The tolerance value originally refers to the value under which the indicating switch shall not be damaged or its characteristics shall not be changed during operation.
Indicating switch with two or more contact elements that cannot be adjusted separately. Different action values and return values may be provided for each contact element. Indicating switch with two or more contact elements that can be adjusted separately may be regarded as a combination of indicating switches. 6.2 Performance requirements
Unless otherwise specified in the relevant standards, the following requirements apply to new and intact electrical appliances. 6.2.1 Action performance
7.2.1 of GB/T14048.1-2000 applies. 6.2.2 Insulation performance
6.2.2.1 Clearance and creepage distance
The minimum values of clearance and creepage distance shall comply with the provisions of Table 6. The table gives the clearance between two live parts (L-L) and between live parts and exposed conductive parts (L-A). The distance between live parts and grounded parts (not considered as exposed conductive parts) can be specified by the L-L value under the corresponding voltage. 6.2.2.2 Insulation resistance
Cold insulation resistance is specified by the product technical requirements. 6.2.2.3 Dielectric strength
