Model compilation principles
Category code
The category code represents the category attribute of the switch and is expressed by a Chinese Pinyin capital letter, as shown in Table 1. Table
Characterizing categories
Code letters
Attached switches
Independently installed switches
Soft cord switches
Micro-ohm structure switches
Electronic switches
Split switches exist in conjunction with appliances and cannot be independent switches, so they do not have separate models. Note: ①
Electronic switches use the letter E, which is consistent with the internationally commonly used letter -. Optional switches
5.1.2 Switch categories not listed in Table 1 can be supplemented according to category types. In principle, the code letters of the supplementary categories should use the first letter of the Chinese pinyin of the first Chinese character of the represented category. When the code is repeated, the first letter of the Chinese pinyin of the second Chinese character is used. If there is still a repetition, the second and third letters of the first or second Chinese character are selected in order. However, the three characters "1", "0" and "X" shall not be used in the code.

5.1.3 If the switch has multiple types of attributes, the most representative code letter should be selected. 5.2 Characteristic Code
Characteristic Code Table The operating mode of the switch is represented by a capital letter of the Chinese phonetic alphabet, see Table 2. 5.2.1
Operating mode represented by the code letter
5.2.2 For operating modes not listed in Table 2, appropriate letters shall be selected as characteristic codes according to the same principle as Article 5.1.2. Y
5.3 Design code
5.3.1 Design codes are used to represent the same category , switches with the same specifications and the same operating method have differences in structural design, appearance and installation dimensions, ambient temperature limits, pollution levels, PTI values ​​and number of operating cycles. 5.3.2 The design code is represented by 1 to 5 Arabic numerals and is issued uniformly by the switch model management department. 5.4 Specification code
5.4.1 The specification code represents the rated current of the switch in A (ampere), and is represented by Arabic numerals with a maximum of 3 digits. See Table 3, Table
Rated current
Digital code
634032251610642
634032251610642
004:003
When the rated current is different from that listed in Table 3, the appropriate number shall be selected as the specification code according to the same principle. 5.4.2
5.4.3 The switch has When there are several groups of rated values, the maximum rated current value corresponding to the highest rated voltage shall be selected as the specification code. 5.4.4 For AC/DC dual-purpose switches, the DC rated value shall be used as the specification code. 5.4.5 The rated current of the basic resistive load shall be used as the specification code for all switches. 001
Note: For loads other than the basic resistive load, such as incandescent load, motor load, capacitive load, etc., the rated current or surge current of each load shall be indicated in the current symbol and shall not be selected as the specification code. Auxiliary code
5.5.1 Auxiliary codes are used to supplement the description of certain structural features, control objects, derivative products, etc. of the switch, and are represented by Chinese pinyin letters and Arabic numerals, with a maximum of 5 digits. For example: the number of poles and digits can be represented by the corresponding Arabic numerals: automatic reset can be represented by the Chinese pinyin letter F; automatic reset with self-locking device can be represented by the Chinese pinyin letter A. The phonetic letter S is used to represent the switch; the one that can be switched forward and backward is represented by a letter; the deep-seated products can be distinguished by the letters A, B, C, D, etc.; the one dedicated to a specific appliance can be represented by the appropriate Chinese phonetic letter representing the appliance, etc. The specific provisions are stipulated by the standards of various switch products. 5.5.2 When the size of the switch is too small to list all the codes in the model and structure in sequence, the auxiliary code is allowed to be listed in a separate line. 5.5.3 When it does not cause misunderstanding, the auxiliary code is allowed to be omitted in the technical documents. Model Example
Example 1: A push button switch with a design code of 2, installed in an appliance, has a rated voltage of 220V AC, a basic resistive load rated current of 10A, a motor load rated current of 4A, 2 poles, automatic reset and self-locking, and its model is: FA210/2S
Example 2: A flip switch with a design code of 9, installed in an appliance. There are several groups of rated values: when AC 220V, the basic resistive load rated current is 1A; when DC 220V, the basic resistive load rated current is 1A; when DC 110V, the basic resistive load rated current is 2A, single pole, its model is: FD9-1/1
Example 3: A push-to-pull soft wire switch with a design code of 3 controls 2 gears of resistive load (total 3 positions including the disconnect position), the rated voltage is AC 220V, the maximum The maximum rated current is 0.4A, 2 poles, and its model is: RU3-04/23
Example 4: A rotary selector switch with a design code of 5, 2 poles and 4 positions, is rated at AC 220V, and the maximum resistive rated current is 2A. Its model is: SZ5-2/24
7 Others
7.1 The switch model should be formulated in accordance with the principles specified in this standard. The design (manufacturing) unit shall apply for it in accordance with the provisions of the "Applicant Method for Applicant Switch Model" and it will become effective only after being reviewed and issued. 7.2 The same product shall not have 2 or more different models. 7.3 Different products shall not have the same model. 7.4 When the appearance and structure of the product have changed significantly, or the technical performance indicators have been significantly improved, a new model should be assigned. Additional notes:
This standard is proposed and managed by the Appliance Switch Branch of the National Technical Committee for Standardization of Electrical Accessories. This standard is drafted by the Shanghai Electric Tool Research Institute. The main drafters of this standard are Qian Naizhi and Dai Hong. 3
