### Explanation:

Our basic switches fall under the category of “wiring equipment-related products” as defined by the Electrical Appliances and Materials Safety Act. However, they do not need to comply with this law as they fall under the category to which the law is not applicable as shown below.

For more information, see the “Interpretation of the Scope of Electrical Appliances and Materials” published by the Ministry of Economy, Trade and Industry, which has the following:  
Those that are designed and manufactured to be incorporated into machinery and equipment and have parts where the charging part is exposed in the electric wire connection terminal are interpreted as “those of a special structure incorporated into the machinery and equipment” and treated as being excluded.
